Question

Solve the following MOSFET problem.

For a MOSFET amplifier circuit shown in Figure Q.1, the transistor parameters are:
Vr=Vos(TH) = 1.5V, k=0.5 mA/V, ra = 0o,
all junction and stray capacitances are neglected except Cwo.
The circuit is to be designed such that:
• The VosQ = 2.79 V
• The input impedance, Zi= 155 k2
• The small signal voltage gain, A,
• The lower -3dB frequency associared with Ch. fici = 20 Hz
° = – 10
The upper -3dB frequency associated with Cwo, THo = 3 kHz
By performing DC and ac analysis.
(ii) Detemine the value of the resistors R¡ and Ry.
(v) Calculate VDsQ-
(vi) Detemine the value of Ci and Cwo.
