Multi-channel time digitizing systems

In this paper we present an overview of a family of Time-to-Digital Converter (TDC) systems developed at HYPRES over the past several years. We have developed three types of RSFQ-based time digitizing systems: an eight-channel multi-hit 30-ps TDC, a two-channel multi-hit 6-ps TDC, and a dual-function multi-hit TDC/ADC. We present results of successful testing of an all-digital TDC up to 33-GHz clo...
