V-FET and SIT . The static induction transistor (SIT) is a three-terminal semiconductor device. Similarly to other active devices (like the bipolar-junction transistor (BJT) or the junction field-effect transistor (JFET), in a SIT the current flow between two terminals (the source and the drain) can be controlled through the third terminal (the gate). MOSFET Amplifiers and High-Frequency Performance Small-Signal equivalent circuit: In many applications, MOSFET is used as a linear (small-signal) amplifier A small signal equivalent circuit for MOSFET is needed to analyze the MOSFET frequency performance. The equivalent circuit is constructed from the basic MOSFET geometry

Common Drain Amplifier or Source Follower Experiments 4. Source Follower as DC Level Shifter Source follower is a voltage follower, its gain is less than 1. The DC transfer characteristic has a slope of less than 1. First let us determine the maximum output voltage. For source follower this occurs when the input voltage V in is at maximum or ... Comparison of the JFET and the BJT An exact comparison of the BJT and the FET is impossible, in general, because the noise perfor-mance of each is so dependent on device parameters and bias currents. The CS and SR Amplifier The circuit for a SR amplifier using an n-channel JFET is given in Figure 6.40a and is reproduced to the right Note that your text describes this amplifier circuit as a common source configuration. The only difference between the SR and CS is the addition of a bypass capacitor (C S) across R S. As Department of Mechanical Engineering.
