Abstract: Aspects of this disclosure relate to an amplifier with at least two chopper amplifier channels in parallel between a shared input and differential nodes. The amplifier can multiplex outputs of the chopper amplifier channels to provide the output of one or more chopper amplifier channels to the differential nodes at a time. In certain embodiments, this can mask dynamic settling errors.

Abstract translation: 本公开的方面涉及具有在共享输入和差分节点之间并联的至少两个斩波放大器通道的放大器。 放大器可以对斩波放大器通道的输出进行多路复用，以便一次提供一个或多个斩波放大器通道到​​差分节点的输出。 在某些实施例中，这可以掩盖动态稳定误差。
