Fast wide output range CMOS voltage reference

摘要

A circuit is disclosed that compensates for changes in temperature as well as for fluctuations in a supply voltage (Vcc) so that voltage reference values generated thereby are maintained at substantially constant levels irrespective of changes in temperature or fluctuations in supply voltage. The circuit is also configured to produce a wide range of voltage reference values so that it can independently service the needs of many different applications. Additionally, the circuit is designed using meal oxide semiconductor (MOS) technology, as opposed to more conventional bipolar technology, so that it “settles down” or generates reference values relatively quickly.
