*D10.45 The MOSFET current-source circuit in Figure P10.44 is biased at V+ = 2.0 V. The transistor parameters are VTN = 0.5 V, kn′ = 80 μA/V2, and λ = 0.015 V −1. (a) Design the circuit such that IREF = 50 μA and the nominal bias current is IO = 100 μA. (b) Find the output resistance Ro. (c) Determine the percentage change in IO for a change in drain-to-source voltage of ΔVDS2 = 1 V. Figure P10.44
