    摘要: A monolithically integratable constant-current generating circuit includes a current-generating circuit having a control terminal and two output terminals, from which currents flow that are bound by a constant proportionality ratio.There is connected to one output terminal the input branch of a circuit having a current mirror and having a current gain which varies with the level of the current itself. A first input terminal of a current-comparator and amplifier circuit is connected to the output branch of the current mirror; a second input terminal is connected to the second output terminal of the current-generating circuit and the control terminal is connected to the output terminal of the current-comparator and amplifier circuit.
