Chopper-stabilized dsm chopping frequency

WebMar 28, 2013 · However, a significant drawback of such amplifiers is a transfer-function notch around the chopping frequency (fchop). This is because their input choppers demodulate signals near fchop to DC, where they are blocked by the input capacitors. This problem is exacerbated by the use of a ripple-reduction loop (RRL) to… View on IEEE … Webthe frequency of the chopping clocks and multiples thereof (as shown in FIG. 1).
