摘要： An amplifying circuit which may be useful in a diamond buffer amplifier (20) or operational amplifier includes an input transistor including an emitter, a collector, and a base coupled to receive an input voltage. An adjustable current source (10) circuit is coupled between a first reference voltage and the emitter of the input transistor. A current source is coupled between a second reference voltage and the collector of the input transistor. An isolation resistor has a first terminal coupled to an output terminal of the adjustable current source circuit and a second terminal coupled to the emitter of the input transistor. A current follower circuit is coupled between the collector of the input transistor and an input terminal of the adjustable current source circuit. A feed- forward capacitor is coupled between the collector of the input transistor and the first terminal of the isolation resistor.

摘要： A low noise charge pump circuit includes a first terminal (8) of a first flying capacitor (Cl) selectively coupled to a first voltage (VCC) during a first recharging phase and a second terminal (7) of the first flying capacitor selectively coupled to a second voltage (GND) during the first recharging phase. The second terminal of the first flying capacitor is coupled to a precharge control circuit (25, 27) during a first parasitic capacitance precharging phase that occurs after the first recharging phase to cause the voltage of the first terminal of the first flying capacitor to equal an output voltage (Vout). The first terminal of the first flying capacitor is coupled to an output conductor (10) conducting the output voltage during a first discharging phase that occurs after the first parasitic capacitance precharging phase. The second terminal of the first flying capacitor is coupled to a discharge control circuit (2, 4) which increases the voltage of the second terminal of the first flying capacitor during the first discharging phase until the output voltage is equal to a regulated value.
