摘要：
A rail-to-rail ping-pong op-amp achieves offset cancellation and 1/f noise reduction without folding of the input spectrum. The clocking scheme minimizes the clock feedthrough and the residual offset due to charge injection. With a clock frequency of 100 KHz, the residual offset is less than 100 mu V, and the input referred noise is about 225 nV/Hz(1/2). The rail-to-rail distortion at 1 kHz is lower than -71 dB. The total silicon area is 610 x 420 mu m(2), and the circuit dissipates 1.5 mW from a single 5 V supply.
