Abstract
A high/low and low/high analogue level converter circuit for integrated circuits in which a high/low converter circuit comprises, supplied at a first voltage value, a converter module which receives a logic input signal of analogue level adapted to this first voltage value and delivers a logic signal inverted and replicated with analogue level adapted to this first voltage value, and, supplied at a second voltage value, a differential converter module which from inverted and replicated logic signals delivers a converted logic input signal with analogue level adapted to second voltage value. The low/high converter circuit comprises, supplied at a given first voltage value, an inverter stage which receives a logic input signal with analogue level adapted to the given first voltage value and delivers an inverted input signal, and, supplied at a second given voltage value, an amplifier converter module which, from inverted input signal, delivers a converted logic input signal with analogue level adapted to the given second voltage value.
