Coarse frequency tuning in a voltage controlled oscillator
Abstract:
Methods and apparatus are presented for performing coarse frequency tuning in a voltage controlled oscillator. The methods and apparatus are directed towards the use of a new voltage controlled oscillator comprising both a binary coding module and a thermometer coding module. The combination of the binary coding module and the thermometer coding module control a capacitance corresponding to a resonant tank which is used to coarse tune the frequency of the voltage controlled oscillator.
