Abstract
A signal regenerator is provided which includes a common mode reference generator and a signal converter circuit. A common mode reference voltage level is generated which is variable in relation to at least one of a process used to fabricate the common mode reference generator, a level of a power supply voltage provided to the common mode reference generator or a temperature at which the common mode reference generator is operated. A signal converter circuit receives a differentially transmitted signal pair including a first input signal and a second input signal and outputs a single-ended output signal representing information carried by the differentially transmitted signal pair. Using a feedback signal from the common mode reference generator, a feedback control block controls a common mode level of the single-ended output signal in accordance with the common mode reference voltage level.
