- Abstract
- A 2.1-2.9GHz LC-VCO based clock generator with a fast automatic frequency control (AFC) circuit is proposed. The fast AFC function is achieved by the frequency multiplication and binary searching algorithm in a 4-bit capacitor array of LC-VCO and completed in 4-cycles of reference signal. The simulation results show that AFC time of only 100 ns, operation frequencies of 2.14 to 2.95 GHz.
