ABSTRACT:
A bandgap reference generation circuit utilizes two feedback loops to maintain the voltage at across the current sources to be essentially the same, such that the reference voltage remains constant over variations in process, temperature, and supply voltage. The accuracy of the reference voltage is maintained even at low supply voltages. Furthermore, the feedback loops increase the output impedance of the current sources, reducing the amount of noise coupling from the power supply, improving power supply rejection ratio.
