Abstract

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.
