WebNov 23, 2016 · Chopping involves the use of two synchronized polarity-reversing choppers [1–4] for precise modulation and demodulation.Each chopper consists of four switches driven by clock signals with two complementary phases at a certain chopping frequency (f chop).In CMOS technology, the switches can be simply implemented by MOSFETs, as … WebMay 3, 2013 · Since 1/f (flicker) noise is merely a slow time-varying offset voltage, choppers also virtually eliminate this increased noise spectral density in the low frequency range. The chopping shifts the base-band signal to the chopping frequency, beyond the input stage’s 1/f region. Thus the low frequency signal range of the chopper has a noise ...
