Abstract
A system for generating a high PSRR bandgap and current reference that includes a bandgap reference circuit for generating a first input and generating a bandgap reference voltage output. A current reference circuit for receiving a second input and generating a reference current. An internal resistor coupled to the first input from bandgap reference circuit and second input of the current reference circuit, wherein the current generated proportional to first input and the second input are generated as a function of the internal resistor. The system also includes a detection/monitoring circuit for bandgap reference output.
