APPARATUS FOR PROGRAMMABLE INSERTION DELAY TO DELAY CHAIN-BASED TIME TO DIGITAL CIRCUITS

摘要

An apparatus for delaying a plurality of chain-based time-to-digital circuits (TDCs). The apparatus includes a plurality of propagation path devices each connected to a respective one of the plurality of TDCs, each propagation path device delays a common start signal by a selectable amount based on a delay selection signal received by the propagation path device, and transmits the delayed start signal to the respective one of the TDCs.
