ABSTRACT:
An output stage of a CMOS comparator is designed to have a limited short circuit current, while maintaining maximum output voltage swing and a low quiescent current. The output stage includes a reference voltage generation circuit, which generates a gate voltage at the output transistor of limited range, so that the short circuit current of the output transistor is limited. In one embodiment, the reference voltage is generated by a plurality of serially connected diodes.
