Abstract

Differential receivers are “stacked” and independently calibrated to different common-mode voltages. The different common-mode voltages may correspond to the common-mode voltages of stacked transmission circuits. Multiple stacks of samplers are connected to the same channels. The clocking of each stack of sampler circuits is phased (timed) such that the samplers in a given stack are not resolving at the same time. Samplers in a different stack and receiving a different common-mode voltage resolve at the same time.
