ABSTRACT:
A generator circuit for a reference voltage independent of temperature variations uses a Brokaw cell biased by a current generator. The generator circuit includes a start-up circuit for delivering a current to the load of the generator using a transistor from the power-on instant until the switching on of the Brokaw cell and the consequent switching-off of the transistor. The circuit further includes a first field effect transistor having a gate coupled to a bandgap voltage node of the Brokaw cell and operatively connected in series with at least one diode between a biasing current generator of the start-up circuit and ground. The circuit also includes a second bipolar junction transistor having a base coupled to the power supply node of the Brokaw cell and operatively connected to a load resistance that is, in turn, connected to the supply rail and to the output transistor of the Brokaw cell for supplying current to the load during the start-up phase.
