Abstract
A circuit capable of quiescent current control, the circuit comprising a first operational transconductance amplifier (OTA) including a first output terminal, a first transistor including a first gate coupled to the first output terminal of the first OTA, a second OTA including a second output terminal, a second transistor including a second gate coupled to the second output terminal of the second OTA, a resistive load including a first terminal coupled to the first output terminal and the first gate, and a second terminal coupled to the second terminal and the second gate, a first current source capable of providing a first current flowing toward the first terminal of the resistive load, and a second current source capable of providing a second current flowing away from the second terminal of the resistive load.
