Abstract
A comparator to provide an output voltage indicative of comparing an input voltage with a reference voltage, where the comparator has an asymmetric frequency response. With an asymmetric frequency response, the bandwidth of the input voltage may be greater than the bandwidth of the reference voltage. A comparator includes a differential pair of transistors coupled to a current mirror and biased by a current source, where in one embodiment, a capacitor shunts the sources of the differential pair. In a second embodiment, a capacitor couples the input voltage port to the gates of the current mirror transistors. In a third embodiment, the comparator utilizes both capacitors of the first and second embodiments.
