Abstract
A termination resistor circuit includes a first and second passive resistive elements coupled in series between a common mode voltage and a signal node, and a plurality of active resistive elements coupled in parallel with the first passive resistive element. The active resistive elements may be selectively enabled by corresponding control signals to provide various numbers of parallel resistances across the first passive resistive element, thereby tuning the termination resistor circuit to a desired resistance value.
