Design of Frequency Synthesizer Using VCO Multi-Phase Signals
VCO 위상신호를 이용한 주파수 합성기 설계
Abstract
In this paper, an improved integer-N frequency synthesizer that can be synthesized into smaller channel space than input signal frequency is presented. The proposed frequency synthesizer also has an characteristics of fast phase locking time. The frequency synthesizer performed in the manner that it divides various outputs of different phases in VCO by means of dividers that have different control signals respectively and then add the divided signal. In order to confirm the characteristics of proposed frequency synthesizer, behavioral and SPICE simulations are performed using C-language and HSPICE respectively.
