Abstract
A circuit configuration for low-power reference voltage generation, is described. The circuit has a programmable voltage source which generates an output voltage which is compared with a reference voltage at predetermined times. Depending on the comparison, at least one signal, which is supplied to a control device, is derived by a calibration device. The control device programs the voltage source in such a manner that the output voltage corresponds to the reference voltage as closely as possible.
