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. (Hint: see section 17.11.2 in the text)
