(a) With reference to the subcircuit of explain why there is no hysteresis if m , 1. (b) Suppose W5 and W6 in the circuit of are lowered from 10 m to 4 m, so that m 5 4y6. Assuming n 5 p 5 0 for simplicity, sketch and label the plots of vO1, vO2, and vO1 2 vO2 versus vI . What is the value of the gain in the vicinity of vI 5 0?
