SIM 8.45 The CMOS amplifier in Fig.8.16(a) is fabricated in the 0.13-µm CMOS process whose parameters are specified in Table K.1. All transistors have L = 0.4 µm and are operated at VOV = 0.15 V, IREF = 100 µA and VDD = 1.3 V.
(a) Find the dc component of vI and the W/L ratios of the transistors.
(b) Determine the small-signal voltage gain.
(c) What is the allowable range of signal swing at the output for almost-linear operation?
(d) If the current-source load is replaced with a resistance RD connected to a power supply as shown in Fig. 8.16(b), find the values of RD and so that ID, the voltage gain, and the output signal swing remain unchanged.
