ABSTRACT:
A C MOS level converter for converting low voltage control signals to equivalent control signals of a relatively high voltage which operates with extremely low power consumption. The level converter has first and second pairs of P-type MOS transistors coupled source to source and drain to drain, the commonly connected sources of each pair being coupled to ground potential and the gate of each outer transistor of each pair being coupled to low voltage control signals of opposite phase. The gate of each inner transistor of each pair is coupled to the common drain terminal of the other pair, and the common drain terminal of each pair is coupled to the drain terminal of a different one of a pair of N-type MOS transistors. The gate of each N-type transistor is coupled to the gate of the associated inner transistor of the first and second pairs. A separate constant current source is coupled to each N-type MOS transistor and to a source of relatively high voltage and a biasing voltage for permanently biasing each constant current source in the conducting state.
