Sedra Chapter 8 *8.48 The MOSFETs in the circuit of Fig. P8.48 K(WIL), = K(WIL), = 1 mA/V and |V|=0.5 V. The resistance R = 1 MQ (a) For G and D open, what are the drain currents ID and ID2? (b) For r=co, what is the voltage gain of the amplifier from G to D? (Hint) are matched, having (c) For finite (V-20 V), what is the voltage gain from G to D and the input resistance at G? (d) If G is driven (through a large coupling capacitor) from a source vaig having a resistance of 20 kQ, find the voltage gain vaVsig (e) For what range of output signals do Q₁ and Q2 remain in the saturation region?
