SIM D 8.5 A current source is implemented using the basic NMOS current mirror with IREF = 25 µA, L1 = L2 = 0.54 µm, W1 = 1.74 µm, and W2 = 4W1. The circuit is fabricated in the 0.18-µm CMOS technology with the parameters given in Table K.1. Determine VOV, IOnominal, VCSmin, and Ro. Also, find IO for VO = 0.2 V, 0.7 V, 1.2 V, and 1.7 V.
