D 2.88 Figure 2.23 shows a circuit that performs a low-pass STC function and is known as a first-order low-pass active filter. Design the circuit to obtain an input resistance of 10 kΩ, a dc gain of 20 dB, and a 3-dB frequency of 200 kHz. Sketch the circuit’s magnitude response indicating the frequency where it is 0 dB.
R1 = 10 kΩ; R2 = 100 kΩ; C2 = 15.9 pF; 2 MHz
