Abstract
This paper presents the design and implementation of low power Pseudo-differential bias-and-input interchange telescopic op- amp architecture. Op-amps sharing between two stages in one channel or across two parallel channels reduce the number of op-amps. The op-amp sharing technique reduces the number of active op-amps by about half and thus reduces the power consumption. In op-amp–sharing architectures, bias-and-input interchanging (BII) technique is used in which the op-amp summing nodes is resetted to remove the effect of residue signals in pipelined ADC. In the BII technique, the pseudo differential (PD) BII op-amp architecture is developed. Pipelined ADC is designed using 180nm technology.
