Abstract
Apparatus and methods for multi-channel autozero and chopper amplifiers are provided herein. In certain configurations, an amplifier includes at least three channels that operate using multiple phases, including at least a non-inverting chop phase, an inverting chop phase, and an autozero phase. The amplifier further includes an autozero and chopping timing control circuit, which at least partially interleaves or staggers timing of the channels' phases. For example, in certain configurations, when one or more of the channels are being autozeroed at a certain time instance, at least some of the remaining channels operate in the non-inverting chop phase or the inverting chop phase.
