Performance Review of High-Quality-Factor, Low-Noise, and Wideband Radio-Frequency LC-VCO for Wireless Communication [Application Notes

Abstract

The rapid growth in the network-communication-system market has placed higher demands on radio-frequency (RF) transceivers. The voltage-controlled oscillator (VCO) is one of the most important building blocks of any communications system, and a high-performance VCO is critical to cover new requirements in communication systems such as required frequency bandwidth recommended by ITU-R, high phase noise performance, power consumption, die size and its cost.
