Abstract :
In this paper, composite replica-tail-feedback (CRF) bias is proposed to prevent the valid window from reducing due to variations of input common mode (CM) level. The CRF bias is applied to a differential static amplifier and a differential clocked receiver. They are fabricated with a 0.1 μm CMOS process and the supply voltage is 1.2 V. When the input CM level changes between 0.5 V and 1.0 V, the static amplifier features output CM level variations of ±2.3% and propagation delay variations of ±7.5% against each average. Under the same condition, the clocked receiver provides zero setup and 60 ps hold, and the alterations of hold are 14 ps.
