7.32 Consider the MOSFET in Example 7.11 when fixed-VGS bias is used. Find the required value of VGS to establish a dc bias current ID = 0.5 mA. Recall that the device parameters are 1 mA/V2, and λ = 0. What is the percentage change in ID when the transistor is replaced with another having Vt = 1.5 V?
VGS = 2 V; –75%
