Abstract
A bandgap voltage reference circuit for generating a bandgap voltage reference. An embodiment comprises a current generator controlled by a first driving voltage for generating a first current depending on the driving voltage, and a first reference circuit element coupled to the controlled current generator for receiving the first current and generating a first reference voltage in response to the first current. The circuit further comprises a second reference circuit element for receiving a second current corresponding to the first current; said second reference circuit element is adapted to generate a second reference voltage in response to the second current. The circuit further comprises an operational amplifier having a first input coupled to the first circuit element and a second input coupled to the second reference circuit element. The circuit also comprises a control circuit comprising first capacitive element and second capacitive element.
