Abstract
A voltage controlled oscillator (VCO) in a frequency synthesizer generates an output signal having a target frequency by being coarse tuned in accordance with a channel code derived through a binary tree search. Thereafter, the output signal of the VCO may be further tuned using a phase lock loop (PLL) circuit. Each stage of the binary tree search includes a comparison step that determines a channel code bit, and another step that confirms that the channel code converges to a final channel code within an established stage range value.
