Abstract
A circuit is designed with a first transistor (,) having a current path coupled between a supply terminal (,) and a first output terminal (,). A second transistor has a current path coupled between the first output terminal and a reference terminal. The current path of the second transistor current path has substantially the same width and length as the first transistor current path. A first comparator circuit (,) has first (,) and second (,) input terminals and a second output terminal (,). The first input terminal is coupled to the first output terminal. The first comparator circuit produces a control signal in response to a voltage between the first and second input terminals. A generator circuit (,) receives the control signal and produces an output voltage at the supply terminal.
