Ans:In FET always input is reverse biased (VGS ), IG=0, there exists minimum IGSS  with high input impedance.It is in the range of Mohms.So, any value of VGS , IG=0. Die Gesichtspunkte der internen und der externen … The MOSFET has a drawback of being very susceptible to overload voltages, thus requiring special handling during installation.The fragile insulating layer of the MOSFET between the gate and channel makes it vulnerable to electrostatic damage during handling. It is a three-terminal unipolar solid- state device in which current is controlled by an electric field as is done in vacuum tubes. This is not usually a problem after the device has been installed in a properly designed circuit. When the positive voltage is applied to the drain to source terminal of JFET and when the gate to source voltage is zero, the Drain current starts flowing and the device is said to be in ohmic region. Calculate the dynamic resistance at -0.5 V, +0.15 V and +0.2 V. of ECE CREC 3 1. Introduction When working with discrete circuit components (as opposed to integrated circuits), it is relatively easy to check for their correct operation and their exact operating characteristics using Ans:In FET the voltage VDS at which the current ID reaches to its constant saturation level is called Pinch-off Voltage, VP. It is preferred during oscillation circuits. The corresponding collector current I C is noted. Analog Electronics: Output or Drain Characteristics of JFET Topics Covered: 1. The family of curves obtained by plotting I C against V CE for each value of I B is called output characteristics. Output or Drain Characteristic.

Output Small Signal Characteristics Experiment-Part1 In this part, we will measure the NMOS threshold voltage. Connect voltmeter and ammeter with correct polarities as shown in the circuit diagram. It is also known as drain characteristics. Ans: In FET conduction due to only majority charge carriers, that is the reason for FET is called as unipolar device. UJT Characteristics 8. Basically, the characteristics are of two types that are output characteristics or drain characteristics, … As such, a FET is a \voltage-controlled" device. Why wedge shaped depletion region is formed in FET under reverse bias gate condition? 4. Connect the NMOS substrate to ground, and the PMOS substrate to V DD. Experiment No.12 Field Effect Transistor (FET) OBJECT: To investigate the FET characteristics . List of Accessories 17 . Ans: It has a relatively low gain-bandwidth product compared to a BJT. EXPERIMENT 6 TRANSISTOR CHARACTERISTICS 6.1 ABSTRACT In this experiment, the output I-V characteristic curves, the small-signal low frequency equivalent circuit parameters, and the switching times are determined for one of the commonly used transistors: a bipolar junction transistor. 5.
