This project goal is to design the millimeter-wave transceiver for automotive collision avoidance radar. The sub-project plays the role of detecting the safety distance, using Doppler effect to design a millimeter-wave transceiver, providing sub-projects three, four, six for a safe distance from the car-judgment to make an active safety in the car driving information. Hence, the precision radar is implemented using 90-nm CMOS technology. The working items include the design of sub-circuits applied in the transmitter and receiver and the antenna in three years.The first year is to establish the system and sub-circuits specifications. Simulate the behavior of the transceiver operates at millimeter-wave. Accordingly, the block diagram of each sub-circuit is developed to satisfy the whole system specification.The second year is to achieve the simulation and implementation of individual sub-circuits. The low-noise amplifier adopts the three-stage cascade architecture to enhance the value of gain. The voltage control oscillator uses an quardrature LC tank circuit to improve the tuning range. The mixer uses the RF-signal amplification to offset the impact of parasitic capacitance. The power amplifier uses E-class architecture to improve PAE and Gain. The previous sub-circuits are integrated all into a single chip. In addition, adopting individual integrated approach, the project is to integrate two sub-circuits into a single transceiver system.The third year is to integrate this sub-project with three, four, six of the main system. Provide a safe distance from the value delivered to the sub-projects. Use the signal generator and vector signal analyzer to determine the characteristics of millimeter-wave transmitter received. Moreover, the study of more advance transceiver such as 94GHz operation band to improve the sensitivity and resolution of the radar receiver.本子計畫之主要是以完成車用防撞毫米波雷達收發機之設計。車用防狀雷達在總計劃中扮演安全測距之角色，利用Doppler效應所測得之距離，提供子計劃三、四、六以供車子安全距離之研判，提供主動安全於車子行車之中。本計劃規劃以90-nmCMOS技術來實現毫米波之雷達。包含接收及發射機等子電路。因此第一年將模擬毫米波的佈局寄生效應，以及建立收發機的系統方塊及各個子電路的系統結合之規格。第二年將每個子電路的模擬、佈局個別實現，包含低雜訊放大器採用三級cascade技術，以提升增益及降低雜訊之值。電壓控制震盪器採用採用4階LC 諧振腔的電路技巧，以改善使用的可調頻寬。混波器採用放大RF端訊號，以抵銷寄生電容的影響 。功率放大器採用E-class，以提昇效率和增益。最後，將所有子電路整合成晶片，率先以個別整合的方式，將其整合到單一收發機。第三年的工作，將整合子計劃三、四、六的系統，將安全距離之值，傳送到上述子計劃，搭配信號產生器及向量信號分析儀以確認整個毫米波收射機之特性。此外，著手於研究更高頻(94GHz)的收發機，使雷達接收機的靈敏度及解析度將有所提升
