Chapter 12, Problem 12.27(choose chapter or problem)
Figure P12.27 shows the CMOS version of the circuit in Fig. E12.11. Find the relationship between I3 and I1 in terms of k1, k2, k3, and k4 of the four transistors, assuming the threshold voltages of all devices to be equal in magnitude. Note that k denotes . In the event that k1 = k2 and k3 = k4 = 16k1, find the required value of I1 to yield a bias current in Q3 and Q4 of 1.6 mA.
