  • 摘要:

    應(yīng)用于激光雷達(dá)(LiDAR)測量系統(tǒng)的單芯片全集成信號處理電路系統(tǒng)的設(shè)計與實(shí)現(xiàn)，對于有效提高激光雷達(dá)整機(jī)測量精度、數(shù)據(jù)率，縮短測量時間，減小測量設(shè)備體積和功耗具有重要的意義。考慮到目前對于信號處理電路系統(tǒng)的研究中較少考慮芯片在實(shí)際使用環(huán)境中的接口問題，基于光電探測器、裸芯片、封裝、傳輸線及測試板等諸多接口影響因素，運(yùn)用協(xié)同仿真分析的方法，在電路系統(tǒng)的實(shí)際工作頻段內(nèi)，建立了一種精確的、能反映激光雷達(dá)信號處理電路系統(tǒng)放大電路芯片真實(shí)應(yīng)用環(huán)境的接口一體化仿真模型，并通過S參數(shù)仿真對其進(jìn)行驗(yàn)證。同時基于CMOS工藝，將設(shè)計得到的放大電路系統(tǒng)進(jìn)行流片，在芯片輸入端承載不同光電探測器寄生負(fù)載的情況下，對芯片性能進(jìn)行測試，仿真結(jié)果與測試結(jié)果吻合較好，驗(yàn)證了該接口模型建立的可行性。

    Abstract:

    The monolithic signal processing circuit system for Light Detection And Ranging (LiDAR) measurement has significant practical values in terms of improving LiDAR measurement accuracy and data rate, shortening measurement time, and reducing equipment size and power consumption. As the environment interface problem is less considered, the appropriate input interface model must be established to break through the technology difficulty to associate circuit system with photodetectors, die chip, package, transmission line, test board and so on in the operating frequency range. By the combination of theoretical analysis and model simulation, the real working environment of circuit systemfor LiDAR signal processing can be simulated reasonably. Furthermore, based on CMOS technology, the signal processing circuit chip is tested with different photodetector parasitic capacitances. The well agreements between simulation and the testing results validate the feasibility of the input interface model.
