Abstract
The present invention relates to a conversion circuit having a differential input in CMOS logic levels, this circuit comprising an input comparator comprising two NPN type bipolar transistors, connected by their emitters and receiving differential input signals on their bases; a CMOS flip-flop comprising two branches each constituted by a P-channel MOS transistor in series, with two N-channel MOS transistors of each branch being connected in order to set the current of these branches at the passing state, the gates of the first N-channel MOS transistors of each branch being connected to the drains of the P-channel transistors of the other branch and to an output terminal. This circuit can be used in plasma panel command operations.
