Title:
CIRCUIT CONFIGURATION FOR DC-BIASED CAPACITORS
Document Type and Number:
WIPO Patent Application WO2003038996
Kind Code:
A3
Abstract:
A capacitive element includes two or more voltage-variable capacitors (varactors) ( C ). The varactors are configured so that they are coupled in series with respect to an applied AC signal (110A-110B) and are coupled in parallel with respect to an applied DC bias voltage (120A-120B). The effective capacitance of the overall capacitive element can be tuned by varying the DC bias voltage.
