Abstract
Systems and methods are provided for generating a stable DC reference voltage that has low sensitivity to operating temperature and supply voltage variations and is stable across process corners using complimentary metal-on-semiconductor field-effect transistors (MOSFETS). In an example implementation, a reference voltage generator circuit is provided that includes complimentary MOSFETs including a first complimentary MOSFET connected to a first node and having a first threshold voltage, and a second complimentary MOSFET connected to a second node and having a second threshold voltage that is greater than the first threshold voltage. The reference voltage generator circuit feeds the first node a first current based on mirroring a second current at the second node and outputs a stable DC reference voltage based on the first and second complimentary MOSFETs and configured operating in respective saturation regions.
