The CMOS amplifier in Fig 1 is fabricated in the 0.13-um CMOS process, whose parameters are specified in Table K.1 (Appendix K) in the textbook. All transistors have L = 0.4-um and are operated at Vov = 0.15 V,IREF = 100 uA and VDD = 1.3 V. (a) Find the DC component of vt and the W/L ratios of the transistors. (b) (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 V
