像素探测器因其优异的位置分辨能力在高能粒子物理实验的内径探测器中有着广泛应用,随着应用场景的发展,许多物理实验要求探测器及其读出电子学也具备高精度时间测量的能力。针对像素探测器时间测量的需求,设计完成了一款具备高事例率处理能力、高精度特点的TDC(Time-to-Digital Conversion) ASIC(Application Specific Integrated Circuit)原型电路,将来可以作为核心组成部分集成到像素探测器前端读出ASIC中。采用粗细结合的方案完成TDC的设计,其中粗时间测量基于计数器实现,细时间测量采用TAC(Time-to-Amplitude Converter)结合ADC(Time-to-Amplitude Converter)的结构实现,基于130 nm工艺完成...

The pixel detector has been widely used in the inner track detector of high energy particle physics experiments because of its excellent position resolution.With the development of physics experiments,many experiments require detectors and readout electronics to have the capability of high-precision time measurement.To reach the requirement of pixel detectors about the time measurement,a TDC(Time-to-Digital Conversion) ASIC(Application Specific Integrated Circuit) prototype with high event rate processing capability and high precision has been designed.It is expected to be integrated with the ...
