Abstract
A driver circuit and receiver circuit to reduce power consumption of a digital signal transfer circuit is described. A driver circuit includes a PFET an NFET and an NFET having a low threshold voltage. An input signal DIN-bar is supplied to a gate of the PFET and a reference voltage Vref is supplied to a gate of the NFET A signal having a small amplitude restricted by Vref is outputted from the driver output DOUT. A receiver circuit having a PFET and NFETs and having low threshold voltages, and an inverter having a PFET and a NOT gate The receiver circuit shifts the level of the signal with the small amplitude, drives it with the inverter and outputs a signal ROUT having a CMOS level.
