20090033371 | AMPLIFIER CIRCUIT FOR DOUBLE SAMPLED ARCHITECTURES - A double sampled switched capacitor architecture as described herein includes an amplifier having two separate inputs corresponding to two separate amplifier sections. The amplifier uses a first differential transistor pair for the first amplifier section, a second differential transistor pair for the second amplifier section, a first tail current bias arrangement for the first differential transistor pair, and a second tail current bias arrangement for the second differential transistor pair. The tail current bias arrangements are driven by a bias switching architecture that alternately activates one tail current bias arrangement while at least partially deactivating the other tail current bias arrangement.
