<p>A bandgap reference circuit uses a pair of parallel loads and an op amp driver circuit. The op amp driver circuit uses NMOS inputs to sense voltage conditions at the loads. The configuration permits low voltage response at low temperatures as a result of the configuration setting operating voltages above a saturation voltage. The op amp driver provides an NMOS output, and a low gain stage converts the NMOS output to an output corresponding to that of a conventional PMOS design.</p> |
