A ping-pong amplifier with reduced glitching is described. The ping-pong
amplifier includes a nulling amplifier coupled to a switching network.
The switching network is used to auto-zero a ping amplifier within a
ping-pong amplifier. The nulling amplifier drives the output of a ping
amplifier to a proper output voltage level during auto-zeroing of the
ping amplifier. By being at a proper output voltage level, glitches
associated with transitioning between a ping amplifier and a pong
amplifier are reduced or eliminated.
