COMPLEMENTARY MOS INTEGRATED CIRCUIT

摘要

PURPOSE:To decrease a spike noise at switching by inserting a resistor between the PMOS and the NMOS of an output pre-stage circuit. CONSTITUTION:An analog switch 9 consisting of parallel connection of the PMOS and the NMOS is connected as a resistor between the drain of a PMOS 7 and the drain of an NMOS 8 of the output pre-stage circuit driving an output circuit comprising PMOS 5 and an NMOS 6. Since the through-current at the switching of the output circuit is decreased remarkably, the spike noise caused by the inductance in the circuit is reduced. Moreover, the power consumption is reduced as well.
