Abstract
An inverter-based comparator, powered between a first supply voltage and a second supply voltage being lower than the first supply voltage, includes a first inverter branch composed of at least one first P-type transistor and at least one first N-type transistor; and a second inverter branch composed of at least one second P-type transistor, at least one second N-type transistor and at least two tuning switches. The first inverter branch and the second inverter branch are configured to compare an input voltage with an internal trigger point, thereby generating a compare voltage at an interconnected node. One of the at least two tuning switches is controlled to isolate the first supply voltage and another is controlled to isolate the second supply voltage to compensate for trigger point shifting.
