Q3 TREF VDD 6+ 5 22 li Va Figure 1: Practical implementation of the common-source amplifier with a current-source load The CMOS amplifier in Fig 1 is fabricated in the 0.13-μm 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 μA and VDD 1.3V. (a) Find the dc component of v, 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'DD as shown in Fig. 1, find the values of RD and V'DD so that ID, the voltage gain, and the output signal swing remain unchanged.
