Title:

A LOW VOLTAGE, LOW POWER BANDGAP CIRCUIT

Document Type and Number:

WIPO Patent Application WO/2013/066583

Kind Code:

A3

Abstract:

A bandgap voltage generating circuit for generating a bandgap voltage has an operational amplifier that has two inputs and an output. A current mirror circuit has at least two parallel current paths. Each of the current paths is controlled by the output from the operational amplifier. One of the current paths is coupled to one of the two inputs to the operational amplifier. A resistor divide circuit is connected to the other current path. The resistor divide circuit provides the bandgap voltage of the circuit.
