Junction Field Effect Transistor (JFET) Simulation in Proteus ISIS

Hello Learners, hope you are doing well. I am here with a new tutorial. We'll discuss about Junction Field Effect transistors. In this tutorial, we will learn the basic Introduction to JFET nad will also have a look at its practical Implementation and simulation in Proteus. Basically, Junction Field Effect is a type of transistor, similar to Bipolar Junction Transistors but they have different characteristics due to some reasons as discussed below:

Introduction to JFET

We Define the JFET as:

"Junction Field Effect transistors or simply JFET is the semiconductor ,Voltage Control, three terminal device that is present in both configurations either N channel or P channel."

JFET  are named so because the the operation of JFET relies on the Field of the input gate voltage thus they are voltage operated devices. The Input of JFET is called Gate whereas, the output is said to be Drain.

Explanation about JFET

Junction Field Effect Transistors are important Devices in the world of electronics. They look similar to the transistors but are different in their Production.

Terminals of JFET:

JFET's have two Ohmic connections at either side of the channels. These channels are called Source and Drain. the Connection of Drain and source is said to be Gate. This is the point where PN Junction is formed. Source and Drain Collectively makes resistive path through which the current Id passes due to the Voltage Vds. The channel is semiconductor due to which current is passed equally well at both sides. But, because of the resistivity of the channel, the voltage becomes less Positive when we move from Drain to Source. Subsequently, the PN junction contains the high reverse bias at Drain as compared to the Source. Thus, the a Depletion Region is formed due to biasing whose width increase with the increase in the Biasing and vise Versa.

Configuration of JFET:

We know that Transistors are made by two type of materials i.e, N type and P type. The Terminals are connected by a current path between Drain and Source. these two terminals work as Collector and Emitter, respectively. Hence we observe two Configurations of JFETs:

1. N-Type.
2. P-Type.

Within the P-Type Configuration, we observe the doping of acceptors. hence holes are abundant in this region. by the same token, N- type configuration contain the doping of the electrons hence we get the faster conduction in N-Type region. We'll use N type JFET for the experiment.

Types of JFET:

Base upon their Production, we classify the JFET in two types:

1. Standard JFET
2. Insulated Gate JFET

The 2nd type i.e, IGJFET is most Commonly called Metal Oxide Junction Field Effect Transistor or simply MOSFET.

Conduction of JFET:

JFET are unipolar Devices and their efficiency mainly depends upon the Conduction of holes and electrons in P-Channel and N-channel, respectively.

 Implementation of JFET in Proteus ISIS

The Junction field effect transistors has very specific characteristics that can easily observed on the graph at a glance. Hence, let's start the simulation for best understanding.

Material Required:

1. Junction Field Effect Transistor (2N3819)
2. DC Power Supply
3. Ground Terminal
4. Current Probe
5. DC Transfer Curve Analysis

Procedure for the characteristics of JFET:

• Fire up your Proteus Software.
• Pick Up the JFET from the Pick Library through the "P" button.
• Set the JFET on the working area.
• Foster the "DC" from the power Generation mood of the Proteus.
• Fix 1 DC power supply at the Gate Terminal and the other on the Drain Terminal.
• Pick the Ground terminal from "Terminal mode" and fix it with the Source.
• At this stage, the circuit should look like the picture given below:

• Place the Current probe taken from the side of the Proteus at the Drain.

One point must be clear here, the direction of the probe should be towards the drain showing that the current passes from the Current source towards the Drain terminal of JFET.

• Name the Gate source as "Vgs".
• Name the Drain power supply as "Vds".
• Mark the Current Probe as "Ids".
• Choose "Transfer" from the Graph mode at the left most bar of the Proteus.
• Click on the Working area and make a window of the "DC Transfer Curve Analysis".
• To get the output, we will drag the Id at the graph area.

• At the instance, we have to set the Graph according to our need. Truss, Double click the graph to edit the Properties.
•  Set the Values according to diagram:

Now, when we simulate the graph by left click>simulate the graph, we find a simulation log.

• Simulate the graph through the Play button.
• Maximize the screen through left click at Graph>maximize and Observe the output.

Observations of JFET Characteristics:

• Vgs applied to the Gate Controls the Current flowing between Drain and the Source.
• No current flow through the Gate hence the Source current that is flowing out of the device is equal to the Drain current moving into the device.

Mathematically,

Is=Id

• We observe the four types of regions here:

1. OHMIC Region: JFET acts like a voltage resistor when voltage VGS =0 because the depletion region at this point is very less.
2. Pinch-off region: Resistance is maximum when Vgs is sufficient to cause the JFET to act as an open Circuit. This region is also called Cut-off region.
3. Saturation Region: In this Region, the JFET becomes the Good Conductor and be controlled by Vgs. The Vds has very less effect.
4. Breakdown Region: We observed that the in this region, the Vds becomes maximum and is controlled.

Advantages of JFET:

• They are replaced by the BJT because they are similar to BJT in characteristics like efficiency , robust, instant operation but are smaller than the equivalent Bipolar Junction Transistors. Thus they are better.
• Due to the size, they have less power consumption and low power dissipation, therefore are ideal to use in ICs and the CMOS range of circuit.
• They have extremely high input Impedance tat can be more than thousands.

Consequently, We learnt about extremely important features of the Junction Field Effect Transistor, Perform the experiments for the characteristics and observed the Advantages of JFETs.

Arduino MKR Vidor 4000 Pin Description

Hope you’ve got a brief idea about this Vidor board. In this section, we’ll cover the description of each pin installed on the microcontroller block side and FPGA block side. Let’s jump right in.

Digital Pins

There are total 22 headers + 25 Mini PCI Express pins installed on the FPGA block side. The PCI Mini Express is a port with programmable pins. There are total 8 Digital pins on the microcontroller block which remain in two states i.e. either HIGH or LOW. When these pins are HIGH they are considered ON and receive 5V and when these pins are LOW they are considered OFF and receive 0V.

Analog Pins

It is important to note that the analog pins on board are not routed through FPGA. These pins are attached to both - FPGA and SAMD. Moreover, using these pins on the SAMD side is totally fine, as long as you're not using these pins as outputs on the FPGA side. On the FPGA block, there is no analog pin applicable. While on the microcontroller block there are 7 analog pins.

PWM Pins

The PWM feature in this board is unique. You can use all pins on the FPGA as PWM pins to control the speed of motors. When these PWM pins are activated, the board produces an analog result with digital means. There are 13 PWM pins on the microcontroller block.

UART Pins

There are two UART pins installed on the microcontroller block side. The Rx is a pin used to receive serial data while Tx is a pin used to transfer serial data. On the FPGA side, up to 7 UART are used depending on the FPGA configuration.

I2C Pins

Two pins SDA and SCL are used for I2C communication. The SDA is a serial data line that carries the data and SCL is a serial clock line used for the synchronization of all data transfer through the I2C bus. Again on the microcontroller block side, there is only one I2C protocol. While on the FPGA side up to 7 I2C protocols can be used.

SPI Pins

The Vidor board comes with one SPI (serial peripheral interface) communication protocol that is mainly used to develop the communication between the controller and other peripheral devices such as sensors or shift registers. There is only one SPI protocol on the microcontroller’s side while up to 7 SPI protocols are used on the FPGA side depending on the FPGA configuration. Two pins… MISO (Master Input Slave Output) and MOSI (Master Output Slave Input) are employed for SPI communication. These pins are used to receive or send data by the controller.
