Abstract
Abstract A full-swing BiCMOS driver comprising an inverter for inverting an input signal, which includes two pairs of NMOS and PMOS transistors to invert an input signal and to prevent current leakage, a full-down controlling part for providing control signals, an output driving part for providing an output, and a delay-inverter for delaying and inverting the input signal which includes a delay part having two transmission gates to serve as resistors. According to the present invention, a full-swing BiCMOS driver which provides a full-swing logic value and prevents any additional power consumption by means of the delaying inverter.
