Abstract
A comparator is presented. The comparator includes an input port for receiving an input voltage; an output port for providing an output voltage; a resistive divider, first and second transistors, and a differential amplifier. The resistive divider has a first node for providing a first voltage and a second node for providing a second voltage. The first transistor has a control terminal coupled to the first node, a first terminal coupled to the input port, and a second terminal coupled to a common node. The second transistor has a control terminal coupled to the second node, a first terminal coupled to the input port, and a second terminal coupled to the common node. The differential amplifier has a first input coupled to the first terminal of the first transistor, a second input coupled to the first terminal of the second transistor and an output coupled to the output port.
