Abstract
A voltage comparator, comprises: a first branch comprising a first transistor, a first resistor (R), and a first current dependent voltage source (VA), wherein a first voltage (V) is applied across the first branch to generate a first current and wherein the first transistor is a diode-connected transistor; a second branch comprising a second resistor (R), a second current dependent voltage source (VB), and a second transistor having a control voltage (V), wherein a second voltage (V) is applied on an end of the second branch to generate a second current; and a third branch for generating a comparator output, wherein a trip point of the comparator output is set to when the first current and the second current are equal and wherein the trip point is a function of the transistors, the resistors, and the current dependent voltage sources of the first branch and the second branch.
