Abstract

A glitch-free time-to-digital converter (TDC) based on Gray code is presented. This architecture can reduce hardware, power consumption, as well as chip area significantly compared to a flash type TDC, while keeping comparable performance and glitch-free characteristics. Its proof-of-concept prototype was implemented on FPGA, and the measurement and simulation results validate the effectiveness of the proposed architecture.

一种基于灰码的时间-数字转换器结构及其FPGA实现
提出了一种基于格雷码的无故障时数转换器(TDC)。与闪存型TDC相比,这种架构可以显著减少硬件、功耗和芯片面积,同时保持相当的性能和无故障特性。在FPGA上实现了概念验证原型,测量和仿真结果验证了该架构的有效性。
