Abstract
A variable leaf capacitor is disclosed. In accordance with some embodiments of the present disclosure, a variable leaf capacitor may comprise a first alternating current coupling capacitor having a first terminal coupled to a first differential node and a second terminal coupled to a first common-mode node, a second alternating current coupling capacitor having a first terminal coupled to a second differential node and a second terminal coupled to a second common-mode node, and a varactor having a bias terminal, a first common-mode terminal coupled to the first common-mode node, and a second common-mode terminal coupled to the second common-mode node, wherein the capacitance of the varactor is based on the voltage from the first common-mode terminal of the varactor to the bias terminal of the varactor and on the voltage from the second common-mode terminal of the varactor to the bias terminal of the varactor.
