【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]:For the digital coding processing after time signal quantization, the traditional coding method has the problem that the high bit error rate leads to the degradation of data quantization precision under the condition of high frequency. Based on the analysis of the source of data error code, this paper sets up an analytical analysis model of error code in different state modes, which includes latch and delay mismatch effects, and compares the binary coding method with the Gray-code coding method. The design method of low bit error rate (LBER) cocode coding is analyzed. Based on TSMC 0.35m CMOS technology, a time-digital converter (TDC) circuit using the same frequency code coding method and its layout design are completed. The test results of multi-item MPW chip show that the BER of the same frequency coding method is obviously lower than that of the traditional coding method under the same condition, which is basically consistent with the theoretical analysis.
