The study of method and circuit for identifying the sequence number of input signals

A new way and circuit for identification of the sequence number of input signals will be introduced. The main function of this circuit is to identify the sequence number of input signals. It can identify the sequence number of each pulse that is included in an input signal series, and also can generate the outputs that correspond to the sequence number of each input signal. The sequence number that can be identified in this circuit is N=1,2,3..., 8. The output signals of this circuit can be used as stop signals of multiple Time to Amplitude Converter (TAC) system, also can be used as stop signals of multiple Time to Digit Converter (TAC) system. The propagation delay of output is tpd≤20 ns. The risetime of output signal is tr≤3.2 ns. (authors)
