Abstract
An inverter circuit for generating an output signal at an output node obtained by inverting an input signal level at an input node includes a common-source MOS transistor having a gate node connected to the input node, a source connected to a predetermined voltage and a substrate gate, a load resistor connected in series with the MOS transistor, and a resistor connected between the gate node and the substrate gate of the MOS transistor.
