Title
Digitale Gatterschaltung mit herabgesetztem Querstrom
Other Title
Digital gate circuit with reduced transverse current - has several drain-source paths of series-connected MOSFETs, transmitting output signal of one circuit gate stage.
Abstract
The output signal of the gate circuit gate stage is substantially a binary signal with sharp, at least steep flank/transition and can be tapped at a junction point of two series-connected MOSFETs with both its binary values. The threshold voltages from a P- and an N-channel MOSFET so overlap that the drain-source paths of the MOSFET, coupled at the junction point are not simultaneously low-ohmic - at ideal switching of the transistors. Preferably the MOSFETs have differently doped channels. Typically at least one transistor, near the low potential, is of the N-channel type. The sum of the threshold voltages may be more than 2V, and the overlap may be up to several volts. USE - For digital circuits. ADVANTAGE - Allows free selection of the threshold voltage of individual transistors.
