Chopping offset cancellation

WebThis application report describes the effects of mismatched components on the input offset voltage, and proposes using an external null circuit to reduce the input offset voltage of an amplifier. It also suggests a means for computing proper values of resistors in the null circuit in order to provide appropriate input-offset-voltage compensation.

WebChopping is the second one of DOC techniques [4,5]. In this technique offset is frequency modulated and removed by a low pass filter which limits the bandwidth of the amplifier and so this technique is not suitable for high bandwidth applications. WebJul 1, 2024 · Static offset cancellation, e.g. by trimming, does not affect noise directly. Dynamic auto-zero can however cut low frequency 1/f noise down to white noise level.
