For designs where tuner-diode matching is critical and space is limited, the ZMDC831BTA and 832BTA dual common-cathode, hyperabrupt varactor diodes report high tolerance C-V characteristics, inherent ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

This file type includes high-resolution graphics and schematics when applicable. 1. Bob Pease built this varactor-input op-amp out of discrete components, based on an old design of Jim Williams. A ...
