An interface - circuit for coupling of a logical low voltage - circuit with a high voltage - output, is realized in a standard - cmos - technology

摘要

The present invention relates to an intermediary circuit between a low voltage logic circuit and a high voltage output stage in standard CMOS technology. The output stage (20) is comprised of two transistors, respectively with N channel and P channel, achieved according to a standard CMOS technology. The intermediary circuit is comprised of a voltage level translator (21) coupled between an input logic circuit SL and said output stage (20). The voltage level translator (21) is achieved according to a standard CMOS technology and is comprised of at least two similar base blocks forming voltage mirrors interconnected in a cross-configuration. Said circuit is used to control transducers, plasma screens and electromechanical actuators.
