Abstract
Rapid switching is provided by a circuit that controls the current passing through a chain of CMOS devices arranged in a series circuit. A node output terminal to the circuit is provided intermediate the chain to control the partially conductive state of two other CMOS devices. Voltages at the output terminal sets one or the other of the two CMOS devices in the current conducting state. That state is a partially conducting state of the CMOS device so that small changes flowing in the current path allows a quick transfer of the operating state to the other device. With this arrangement, discharging of large capacitances is avoided by using the small current changes to rapidly switch between the partially conducting CMOS devices.
