Circuit for providing a reference voltage
Abstract:
A circuit for providing a reference voltage, including a first transistor of bipolar type, the emitter of which provides the reference voltage and the collector of which is connected to a first supply pole, a second MOS-type transistor, the drain of which is connected to the base of the first transistor and the source of which is connected to a second supply pole, a control block, an output of which is connected to the gate of the second transistor and an input of which is connected to the emitter of the first transistor, a capacitor connected to the output of the control block and coupled to the first supply pole via a first impedance, and a second impedance connected on the one hand to the second transistor and on the other hand to the connection point between the capacitor and the first impedance.
