CMOS reference circuit using field effect transistors in lieu of resistors and diodes

摘要

A CMOS reference circuit using field effect transistors (FETs) is described. A first plurality of FETs is coupled in series, source node to drain node. A second plurality of FETs is also coupled in series, source node to drain node. The first and second plurality of FETs are coupled such that a specified total voltage drop across the first plurality of FETs is realizable. The combination of the first and second plurality of FETs are usable as a replacement for a resistor. The circuit can also include a FET configured so that it is usable as a replacement for a diode.
