This is the first of a two part series that discusses certain fundamentals in voltage-Controlled Oscillator design.
October 10, 2008
A voltage controlled oscillator or VCO is an oscillator that can be frequency controlled by an external voltage. The external voltage is called a tuning voltage and it is typically connected to a voltage variable capacitor (varactor) within the resonant oscillator circuit. As the voltage changes, the capacitance of...Read More
