11.49 The feedback transconductance amplifier in Fig. P11.45(a) uses a differential voltage amplifier VE 11.3 with a gain μ and a very high input resistance, and a MOSFET Q having 8,5 mA/V and r, = 20 k2. Design the circuit to obtain an ideal closed-loop transconductance of 10 mA/V and an output resistance R of 5 MQ. What are the values required for R, and u? Also, what is the actual value obtained of the closed-loop transconductance?
