摘要

摘要: 对于时间信号量化后的数字编码处理，传统编码方法高频条件下存在高误码率导致数据量化精度退化的问题。该文从数据误码根源分析入手，建立起不同状态模式下包含锁存和延迟失配效应的误码解析分析模型，并在二进制和格雷码编码方法对比的基础上，分析了低误码率的同频码编码设计方法。基于TSMC 0.35 ?m CMOS工艺，完成了采用同频码编码方法的时间数字转换器(TDC)电路及其版图设计，多项目晶元(MPW)芯片的测试结果表明：同频编码的误码率相比同等条件下传统编码方法的误码率明显降低，并与理论分析基本吻合。

Abstract: In the data processing of quantified time signal, traditional encoding method in high frequency is faced with the problem of high Bit Error Rate (BER) affecting the datas quantitative accuracy. This paper presents BER mechanism analytical model according to the analysis of the causes of bit error, which takes both data latch and delay mismatch effects of different state pattern into consideration. And the analysis of same frequency coding mode with low BER is put forward based on the comparison of the binary and Gray coding method. The circuit and layout designs of Time to Digital Converter (TDC) with same frequency coding mode are implemented in TSMC 0.35m CMOS process. The test results of the Multi Project Wafer (MPW) chip show that BER of the same frequency coding mode is effectively reduced compared with traditional encoding modes under the same conditions.
