A diode-connected FET can be viewed as a shuntseries feedback circuit with unity feedback factor (b 5 1). A load placed inside the feedback loop as in Fig. P7.30 will see a resistance Ro@Rs (this, so long as the voltage developed by the load is small enough to prevent vDS from dropping below VOV). Use the shuntseries procedure to estimate Ro and the gain Asc 5 io/ii , if Rs 5 10 kV and IBIAS has been adjusted for ID 5 1 mA. Assume k 5 1.5 mA/V2 and


5 0.02 V21 .
