NMOS PTAT generator and voltage reference

A reference generator system can include a PTAT circuit coupled to a signal supply node and configured to provide a voltage reference signal or a current reference signal that is based on a physical characteristic of one or more components of the PTAT circuit and a correction signal. The system can...

More Information
Summary:A reference generator system can include a PTAT circuit coupled to a signal supply node and configured to provide a voltage reference signal or a current reference signal that is based on a physical characteristic of one or more components of the PTAT circuit and a correction signal. The system can include a CTAT circuit coupled to the PTAT circuit and configured to provide the correction signal to the PTAT circuit. In an example, the reference generator system can be implemented at least in part using NMOS devices that comprise a portion of an indium gallium zinc oxide (IGZO) substrate.
