With the above dc values, we find the following small signal parameters g m = 2 I D=V ov = 2 (500e 6)=(0.4082) = 2.449mA=V r s = 1=g m = 1=(2.449e 3) = 408.2 rBJT. There are two types of MOSFET and they are named: N-type or P-type. BJT is of two types and they are named as: PNP and NPN. MOSFET is a voltage-controlled device. BJT is a current-controlled device. The input resistance of MOSFET is high. The input resistance of BJT is low. Used in high current applications.May 22, 2022 · An AC equivalent of a swamped common source amplifier is shown in Figure 13.2.2. This is a generic prototype and is suitable for any variation on device and bias type. Ultimately, all of the amplifiers can be reduced down to this equivalent, occasionally with some resistance values left out (either opened or shorted).

Mar 22, 2021 · Analyze small signal combination BJT/JFET amplifier circuits. Discuss applications that make use of the JFET's ohmic region. 11.1: Introduction. 11.2: Simplified AC Model of the JFET. 11.3: Common Source Amplifier. 11.4: Common Drain Amplifier. 11.5: Multi-stage and Combination Circuits. 11.6: Ohmic Region Operation. 11.7: Summary. The depletion MOSFET circuit, however, has much higher input impedance than a similar JFET configuration. While a BJT device controls a large output (collector) current by means of a relatively small input (base) current, the FET device controls an output (drain) current by means of a small input (gate-voltage) voltage.
