Chopping offset

WebThe chopper modulation technique is widespread and essential to mitigate 1/f noise and other low-frequency noise, such as popcorn noise, voltage offsets, and drifts. It is particularly used for sensitive acquisition of relatively weak biopotentials such as EEG, which requires very low input-referred noise, less than 1-2 μV rms. WebThis circuit operates in two clock phases: phi1 and phi2. In phi1, the amplifier is auto-zeroing and its offset will be sampled in capacitor Cc. Vin is sampled in C1 and C2. In phi2, the amplifier will do the amplification. Clearly, the feedback factor of the amplifier in phi1 and phi2 is different.
