Abstract
Reference voltage circuits and methods for designing the same are provided. The reference voltage circuit includes: a reference core unit configured to output a reference voltage; a main amplification unit connected to the reference core unit and configured to form feedback to the reference core unit; and a feedforward amplification unit connected to the main amplification unit and configured to form feedforward to the main amplification unit. The reference core unit, the main amplification unit, and the feedforward amplification unit form a third-order negative feedback loop to improve a power supply rejection ratio of the reference voltage.
