ABSTRACT:
An analog-digital hybrid integrated circuit includes: an analog ground terminal set to provide an intermediate potential between a power source potential and a ground potential, a by-pass capacitor provided between the analog ground terminal and a ground terminal (or a power source terminal); and level comparator for comparing the potential on the analog ground terminal with prescribed threshold voltage and for providing high (or low) level voltage provided that the potential on the analog ground terminal is lower (or higher) than the prescribed threshold voltage whereby, the output voltage from the level comparator is supplied to an internal logical circuit as a reset signal.
