N-path filter having N of 4,Q of 500, and voltage gain of 2 uses DG5O9 four-channel CMOS differential multiplexer having necessary pairs of analog switches and decode logic. Dual D flip-flop generates 2-bit binaly sequence from 20-kHz clock signal. Bandwidth is about 10 Hz for 3 dB down, centered on 5 kHz.- Analog Switches and Their Applications, Siliconix, Santa Clara, CA, 1976, p 5-15-5-17.
