Design of CMOS Dual-Modulus Prescaler and Differential Voltage-Controlled Oscillator for PLL Frequency Synthesizer

PLL 주파수 합성기를 위한 dual-modulus 프리스케일러와 차동 전압제어발진기 설계

This paper introduce a different-type voltage-controlled oscillator (VCO) for PLL frequency synthesizer, And also the architecture of a high speed low-power-consumption CMOS dual-modulus frequency divider is presented. It provides a new approach to high speed operation and low power consumption. The proposed circuits simulate in 0.35 um CMOS standard technology.
