D 9.88 In a current-mirror-loaded differential amplifier of the form shown in Fig. 9.32(a), all transistors are characterized by k’W/L = 4 mA/V2, and ∣VA∣ = 5 V. Find the bias current I for which the gain vo/vid = 20 V/V.
Given the PMOS circuit in the Figure below, with parameters as listed. VDD =6 V, |Vtp| = 0.7 V, kp
This is a Resistive load PMOS inverter. R = 1k CL = 10pF a) Size the PMOS so that the inverter is symmetrical. Solve these questions for the size you have found in a). If you cannot solve a), assume (W/L) is 20 . b) Calculate tpHL. c) Draw VTC and mark the important points. d) Calculate VOH and VOL. e) Propose a method to solve for VIL and VIH. Write the required expressions. Don't forget to write the operating region of PMOS.
