Design of Voltage Control Oscillator for K-band FMCW Radar System
, 2010 本論文利用0.18微米互補性金屬氧化物半導體(CMOS)製程，提三個24GHz微波壓控振盪器應用在K頻段之調頻連續波(FMCW)雷達系統。電路設計方面，三個壓控振盪器皆包含兩個調頻機制，其一為粗調機制，具有較大調頻範圍，用來修正震盪頻率並可與鎖相迴路結合，另一為微調機制，設計較小的調頻範圍，以符合系統調頻之應用。在第三章中，第一個壓控振盪器採用二倍頻訊號輸出，並與後端四級放大器結合，以提供足夠的本地訊號輸出功率給後端混頻器使用；第二個壓控振盪器則為基頻震盪器，並包含一溫度補償之偏壓電路 ...
