Optical interconnects have attracted much research attention in recent years owing to potential performance and power-consumption improvements over traditional electrical connectivity. A complete ...

Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...

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 ...
