1. The common source amplfier shown below uses a dc-coupled input and the load capacitance has been removed. Assume that the high-frequency cutoff (-3dB) frequency f. is determined chiefly by R and the total input capacitance, which consists of Cg in parallel with the Miller effect capacitance reflected nto the input. Calculate and show the M coupling and bypass capacitors shown in the circuit can be treated as short-cicuits t capacitance, then estimate fs For this analysis, the R 10k...

Shown below is a single stage common emitter amplifier with a unipolar dc power supply using an 2N3904 NPN BJT as the active device. It is specified that V+ 40 V, C1 C2CE 100uF, Ro-7.5 k2, REi-5.1kS2, and Ri - 36k52. Design the circuit so that the dc collector current is 2 mA and the magnitude of the small-signal midband voltage gain is 32.3. For the design calculations assume that the base-to- emitter dc voltage drop is 0.65 V, the...
