Classification: CPC G  H | IPC G  H

Claim 11:
12. The circuit of claim 11, wherein the signal generator includes:
a logic gate coupled to the crude bandgap generator, in which the logic gate is configured to generate a threshold voltage controlling the first, second and third switches;
an eighth beta transistor having first, second and third terminals, in which the second terminal of the eighth beta transistor is coupled to the crude bandgap generator and to the logic gate, and the third terminal of the eighth beta transistor is configured to receive a bandgap voltage that is a voltage across the bandgap resistor; and
a ninth beta transistor having first, second and third terminals, in which the first terminal of the ninth beta transistor is coupled to the ground terminal, the third terminal of the ninth beta transistor is configured to receive an output voltage that is a voltage at the output terminal of the amplifier, and the second terminal of the ninth beta transistor is coupled to the first terminal of the eighth beta transistor.
