7.73 The overall voltage gain of a CS amplifier with a resistance Rs = 200 Ω in the source lead is measured and found to be −10 V/V. When Rs is shorted, but the circuit operation remains linear, the gain doubles. What must gm and RD be? What value of Rs is needed to obtain an overall voltage gain of −16 V/V?
5 mA/V; 4kΩ; 50Ω
