Wideband VCO composed of CD4007

Published:2011/4/8 2:59:00 Author:Ecco | Keyword: Wideband , VCO | From:SeekIC

The VCO is shown as the chart. The voltage-controlled signal Vi provides a DC voltage with the changing of frequency and phase to the varactor VDl ~ VD3 and from the low-pass filter Rl ~ R3. The voltage is decided by the VCO (voltage controlled oscillator) output frequency of the inductor L, capacitor C3, C4 and varactor diode VDl ~ VD3 and IC (CD4007).
