Abstract
A comparator circuit comprising a transconductance stage that senses a first and a second input voltage and a transresistance stage that senses the current output of the transconductance stage while limiting a voltage swing at the output of the transconductance stage. The transresistance stage generates an output voltage at an output node that indicates whether the first or the second input voltage has a greater magnitude.
