    • Timing accuracy of a TDC can be improved. An apparatus for inserting delay according to an embodiment includes a signal generating circuit, a plurality of carry elements, and a delay chain circuit. The signal generating circuit is configured to generate a start signal. The plurality of carry elements are connected as a chain, and each of the carry elements has an input to receive a stop signal. The delay chain circuit includes one or more delay modules selected from the plurality of carry elements, at least one feedback line connected between at least one of the delay modules and the signal generating circuit, and a plurality of enable inputs. Each of the plurality of enable inputs is provided in a respective one of the delay modules. The delay chain circuit is configured to generate an amount of delay based on a delay selection signal that is received at the enable inputs and that selects the amount of delay, and is configured to provide the selected amount of delay to the signal generating circuit, which is configured to incorporate the delay into the start signal.
    • 可以提高TDC的定时精度。 根据实施例的用于插入延迟的装置包括信号发生电路,多个进位元件和延迟链电路。 信号发生电路被配置为产生起始信号。 多个进位元件作为链条连接,并且每个进位元件具有用于接收停止信号的输入。 延迟链电路包括从多个进位元件中选择的一个或多个延迟模块,连接在至少一个延迟模块和信号发生电路之间的至少一个反馈线以及多个使能输入。 多个使能输入中的每一个被提供在相应的一个延迟模块中。 所述延迟链电路被配置为基于在所述使能输入处接收到的延迟选择信号产生延迟量并选择所述延迟量,并且被配置为向所述信号发生电路提供所选择的延迟量,所述延迟选择信号 被配置为将延迟并入起始信号。
