OA-11 A Tutorial on Applying Op Amps to RF Applications (Rev. B)

WebIt is interesting to consider the effects of a chopper amplifier on low frequency 1/f noise. If the chopping frequency is considerably higher than the 1/f corner frequency of the input noise, the chopper-stabilized amplifier continuously nulls out the 1/f noise on a sample-by-sample basis. Theoretically, a chopper op amp therefore has no 1/f noise. WebTo use an op-amp at high frequency, it is necessary to take two factors into consideration: slew rate and cut-off frequency (unity gain). Slew rate (SR): Even when the ideal rectangular waveform (a fast-rising signal) is applied to the input of an op-amp, its output … dachtheater cordula nossek
