HIGH SPEED, HIGH CURRENT GAIN VOLTAGE BUFFER AND METHOD |
摘要 |
<p>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.</p> |
