ABSTRACT:
A reference level generator in integrated circuit form comprises at least one first current circulation arm in which there are, in series, an N channel transistor and a P channel transistor, one of which is referred to as a reference transistor. The reference transistor has a drain connected to a gate in normal mode, the gate being connected to an output of the generator. Standby mode transistors are interposed between each current circulation arm and a supply terminal, and a mode control input gives a mode signal that turns the standby transistors off in standby mode and turns the standby transistors on in normal mode. A transistor controlled by the mode signal may be connected between the output and a non-floating reference potential, or a pass-gate may be inserted between the gate and the drain of the reference transistor, this gate being controlled by the mode signal to be off in the standby mode.
