| description | The invention relates to the field of time measurement, in particular to an ISERDES-based multi-time measurement type TDC device and a measurement method, an input pulse signal is converted into periodic oscillation by using internal resources such as an IDELAY hardcore, the purpose of improving the measurement precision is achieved through leading edge moments of multi-time measurement signals, and performance testing is performed on TDC by using a Kintex7-series FPGA. Test results show that the TDC time resolution is improved to 30 ps RMS, and most PET application requirements can be met; the TDC device has the advantages of being high in integration degree, high in measurement precision, simple in structure, easy to transplant and the like, and is suitable for PET application requirements.
本发明涉及时间测量领域，尤其涉及一种基于ISERDES的多次测量型TDC装置及测量方法，利用IDELAY硬核等内部资源将输入脉冲信号转换为周期性震荡，通过多次测量信号的前沿时刻达到提高测量精度的目的，利用Kintex-7系列FPGA对该TDC进行了性能测试，测试结果表明，该TDC时间分辨率提升至30 ps RMS，可以满足大部分PET应用需求；该TDC装置具有集成度高、测量精度高、结构简单和易于移植等优点，适合PET应用需求。 |
