SERIAL CAPACITANCE TUNER

摘要

An impedance matching network comprises a first signal terminal configured to receive a signal from a source circuit and a second signal terminal configured to provide the signal to a load circuit. The network further comprises a series branch comprising a variable capacitive component between the first signal terminal and the second signal terminal. The variable capacitive component comprises a plurality of capacitive portions connected in series, wherein at least one of the capacitive portions comprises a switching element comprising a stack of series connected transistors. The impedance matching network also comprises a control component configured to control a capacitance of the variable capacitive component by controlling the at least one of the capacitive portions based on a predetermined algorithm.
