(a) Assuming fS in Fig. P5.49 is suffi ciently high to make the switching process appear as virtually continuous at the signal frequency, derive the transfer function H 5 VoyVi and show that the circuit is a low-pass fi lter with gain.7 What are the expressions for its dc gain and its 23 dB frequency? (b) If fS 5 1 MHz, specify suitable capacitance values for a low-frequency gain of 2 V/V and a 23 dB frequency of 10 kHz under the constraint C1 1 C2 1 C3 530 pF.
