Complementary MOS driver device.

摘要

A high current CMOS driver device including a raised cosine signal generator for generating a raised cosine signal waveform and an input circuit arrangement (26) for controlling the raised cosine signal generator is described. The raised cosine signal generator includes an output node (VOUT) to which a controlled chain of CMOS inverters are connected. The input circuit arrangement accepts an input signal (VIN), converts it into appropriate signals which drive respective inverters (10,10 min ) so that simultaneous conduction of inverter pairs is prevented. This device minimizes ground bounce, electrical noise and radiation problems caused by large current transients or spikes (di/dt) that usually accompany such circuits. <IMAGE>
