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). [0005] Several methods have been used to reduce chopping-related ripple associated with a chopper-stabilized am-plifier. One method, described in A. Bakker and J. H.

WebTo reduce the CFIA's own offset and 1/f noise, a chopper stabilization technique is implemented. To attenuate the output ripple caused by chopper up-modulation, a ripple reduction loop (RRL) is employed. A multipath architecture is implemented to compensate for the notch in the chopping frequency band of the transfer function. WebThe usability of this circuit is demonstrated for a 500 kHz rectangular signal with an amplitude of only approximately 2 mV and a chopping frequency of 20 MHz. A significant decrease of the...
