利用MEMS电子器件的高速性能，开发了具有皮秒时间分辨率的时间数字转换器（TDC）。我们已经设计并成功地测试了预分频器电路，用于将TDC分辨率首先提高到5 ps，然后降低。这些电路被设计为充当使用二进制计数器对时钟周期进行计数的ADC的游标。一个预分频器电路已经证明了在20 GHz的时钟频率下的5 ps分辨率。
The high-speed capability of superconductive electronics is being harnessed to develop a time-to-digital converter (TDC) with picosecond time resolution. We have designed and successfully tested prescaler circuits for improving TDC resolution first to 5 ps, and then below. These circuits are designed to act as a vernier for a superconductive TDC that counts clock periods using a binary counter. One prescaler circuit has already demonstrated 5 ps resolution at a clock frequency of 20 GHz.
