varactorzodilla
Varactorzodilla is a term used in semiconductor engineering to denote a hybrid electronic component that combines the voltage‑dependent capacitance characteristics of a varactor diode with the adjustable resistance function of a variable resistor. The device, first introduced in peer‑reviewed literature in 1989, is manufactured by integrating a silicon–based doped‑junction varactor with a polysilicon channel whose resistance can be tuned by an external control voltage. Unlike conventional varactors, the varactorzodilla allows simultaneous tuning of capacitance and resistance, providing a single‑shot solution for adaptive filter and oscillator design.
The varactorzodilla typically consists of a shallow p‑n junction defined on a highly doped silicon substrate
This component has been adopted in RF integrated circuits for locally oscillated signal matching, adaptive impedance
