Abstract
A comparator having first and second stages can provide component offset compensation and improved dynamic range. The first stage can receive first and second input signals and produce first and second output signals. The second stage can be coupled to the first stage to receive the first and second output signals at first and second input terminals of the second stage. The second stage can provide a voltage to the first and second terminals that differs from the supply voltage by less than a voltage of a diode drop. The comparator is operable to receive input voltages that reach the supply voltage.
