Abstract
A voltage controlled oscillator (VCO) has a VCO core and a tuning bank. The tuning bank includes first and second tuning capacitors. A main switch is coupled between the first and second tuning capacitors. The tuning bank also includes control switches that receive a control signal to selectively activate the tuning bank. The main switch receives a level-shifted control signal to activate the tuning bank.
