Abstract:
A method and apparatus are provided. The apparatus may be a capacitive element for adjusting a net capacitance of a circuit. The apparatus may be configured to be coupled to the circuit. The apparatus may be configured to adjust the net capacitance of the circuit to decouple common mode and differential loop bandwidth adjustment of the circuit. The capacitive element may include a pair of cross-coupled capacitors configured to be coupled to differential nodes of the circuit, and a pair of negative gain buffers coupled to respective capacitors.
