AMPLIFIER APPARATUS AND METHODS USING VARIABLE CAPACITANCE DEPENDENT ON FEEDBACK GAIN |
摘要 |
An apparatus includes an operational amplifier circuit comprising at least one operational amplifier and a feedback circuit coupled between the output terminal and input terminal of the operational amplifier circuit and configured to apply a feedback gain to an output signal at the output of the first operational amplifier. The apparatus further includes a variable compensation capacitor coupled to the output terminal of the operational amplifier circuit and configured to vary a capacitance thereof responsive to the feedback gain.
