Chapter 3, Problem 24E
The circuit shown in Fig. 3.65 includes a device known as an op amp. This device has two unusual properties in the circuit shown: (1) Vd = 0 V, and (2) no current can flow into either input terminal (marked “−” and “+” inside the symbol), but it can flow through the output terminal (marked “OUT”). This seemingly impossible situation—in direct conflict with KCL—is a result of power leads to the device that are not included in the symbol. Based on this information, calculate Vout. (Hint: Two KVL equations are required, both involving the 5 V source.)

Problems
A.1 The square-law modulator is a device for the generation of DSB-PC-AM signals. In the square-law modulator, the sum of the modulating signal and the carrier wave
forms the input signal to a nonlinear device. The output signal of the nonlinear device is a linear combination of the input signal and the square of the input signal. The
output signal of the nonlinear device is then band-pass filtered. The BPF has a center frequency that is the same as the carrier frequency and a bandwidth that is twice
the message bandwidth. Show the output of the BPF is a DSB-PC-AM signal, and determine a requirement between the carrier frequency and the message bandwidth
that must be satisfied.
Give the current voltage relationship of the D-MOSFET and E-MOSFET.
