Abstract

A detailed frequency analysis of Power Supply Rejection (PSR) in Brokaw bandgap voltage reference is carried out. The knowledge of the frequency behavior in a voltage reference becomes mandatory to the designer especially in RF or digital environment where disturbs coming from supply lines becomes more evident. Precise and simple models, useful for pencil and paper analysis, are developed and a compensation technique for improving the circuit frequency performance is also discussed. Results are validated by comparing the implemented models with the actual circuit by means of the SPECTRE simulator
