circuit of voltage band - gap reference series

摘要

a first and a second bipolar diode have respective servers connected to terminals connected to respective terminals opposed mass and piloted by their constant current generators and diversand between them.the two transistors are allowed to fly means supplements - sommatori comprising: (a) a first capacitor connected between a common node and a first switch to connect alternatively opposite terminalsthe two transistors; (b) a second capacitor connected between said common node and a second switch act to connect alternatively at the terminal opposite the second servers, and the mass; and (c) amplificatore; (d) a first switch connected between the output and the input of said amplifier.according to the invention, a second switch is connected between the said first common node and the entry of said first amplifier.
