Intermediary circuit between a low voltage logic circuit and a high voltage output stage in standard CMOS technology

An intermediary circuit formed between a relatively low voltage integrated logic circuit and a relatively high voltage output stage with an output for controlling at least one of a transducer, a plasma screen and an electromechanical actuator, said high voltage output stage comprising a CMOS device with a N type channel transistor and a P type channel transistor which are both coupled to said output of said high voltage output stage, wherein said intermediary circuit comprises a CMOS translator device coupled between an output of said low voltage integrated logic circuit and an input of said high voltage output stage, said translator device comprises at least two identical integrated circuit elements which are interconnected with one another in cross-configuration to form voltage mirrors, said voltage mirrors comprise at least a first relatively low level transistor of the P type channel and a second NMOS-HT type transistor;

• a drain of said first relatively low level transistor is connected to a drain of said second NMOS-HT type transistor, to a gate of said first low level transistor and to an output voltage to be supplied;
• a relatively low level input voltage is connected to a gate of said second NMOS-HT type transistor, and a relatively high level voltage supply is connected to a source of said first relatively low level transistor as well as to a source of a third transistor, of the P type channel, connected in parallel with said first relatively low level transistor;
• a relatively high level voltage input is connected to a gate of said third transistor;
• and a source of said second NMOS-HT type transistor is connected to ground.
