Abstract
A novel terminating differential bus receiver with automatic compensation for process, voltage, and temperature variation is presented. A termination circuit is connected internal to the integrated circuit to the input of a differential receiver in parallel with a transmission line connectable to the receiver. Both the termination circuit and the differential receiver are implemented with at least one p-channel transistor and at least one n-channel transistor, such that the p-channel transistors of the termination circuit and receiver and the n-channel transistors of the termination circuit and receiver are ratioed to vary similarly under PVT variation.
