Chopper-Stabilized Instrumentation Amplifier with Automatic Frequency ...
WebWhat is the nominal chopping frequency used by the these devices? Answer: The chopper-stabilized amplifiers (ISL28133, ISL28134, ISL28233, and ISL28433) use a chopping frequency of about 100kHz. The chopping frequency of the architecture impacts several performance parameters. 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 … thorngrafton northumberland
