摘要： In one embodiment, a parasitic capacitance compensation circuit for a switch is disclosed that includes a first inductor operably coupled between a first terminal and a second terminal, and a second inductor operably coupled between the first and second terminals and parallel to the first inductor. The second inductor is switched in when a peak voltage on the first and second terminals falls below a first voltage. The first inductance tunes out substantially all of a parasitic capacitance of the switch when the switch is OFF and the peak voltage is above the first voltage. The first and second inductances collectively tune out substantially all of the parasitic capacitance of the switch when the switch is OFF and the peak voltage is below the first voltage.

摘要： In one embodiment, an impedance matching network includes a variable reactance circuit having fixed reactance components and corresponding switching circuits. Each switching circuit includes a diode and a driver circuit. The driver circuit includes, coupled in series, a biasing current source positioned to provide a bias current to bias the diode, a first switch, a second switch, and a resistor. For each diode of each switching circuit, the control circuit is configured to receive a value related to a voltage drop on the resistor and, based on the value related to the voltage drop, adjust the bias current being provided by the biasing current source.

摘要： In one embodiment, an impedance matching network includes an electronically variable reactance element (EVRE) comprising discrete reactance elements and corresponding switches. The switches are configured to switch in and out the discrete reactance elements to alter a total reactance provided by the EVRE. A monitoring circuit is operably coupled to the EVRE. For each discrete reactance element, the monitoring circuit monitors a value related to the discrete reactance element or its corresponding switch. Upon determining the monitored value exceeds a predetermined amount, the monitoring circuit the discrete reactance element of the EVRE from switching in or out.
