The circuit consists of two product modulators followed by a
band- pass filter. We assume W=20 KHz, f1 = 100 KHz, and f2 = 50
KHz.
If the passband of the filter (for positive
frequencies) is between 80 kHz and 180 kHz, the output of the
filter will:

4. The switched-capacitor filter implementation of a two-integrator loop is shown below. Assume a clock frequency of fe 100 kHz, and C-C2-5 pF Ca (by (a) An optimally flat low-pass response is realized when Q 1/V2 and wan w.Design the circuit so the 2d integrator's output is an optimally flat low-pass function where w1000 and the DC gain is 1.
