    摘要: A device (10) for determining the number of discrete events represented by an input signal is provided. The input signal may, for example, comprise pulses representing photons arriving at a detector. The device (10) may comprise a plurality, n, of comparator circuits (14) for reading the signal. For each comparator circuit (14) from i=1 to i=n, the i
    th comparator circuit (14) has a corresponding threshold value which the amplitude of a pulse representing i discrete events will exceed, but which the amplitude of a pulse representing i-1 discrete events will not exceed. Each comparator circuit (14) is arranged to output a first value when the input signal exceeds its threshold value and a second value when the input signal is less than its threshold value. The device (10) includes a counter (16) for counting the number of outputs of the first value that have been output by the plurality of comparator circuits (14).

    摘要: A multiple phase clock generator includes a ring of an even number of phase cells, each phase cell generating a separate phased clock signal. Each phase cell supplies its phased clock signal and a prebias output signal in response to concurrent assertion of an enable signal and a prebias output signal from a preceding phase cell on the ring. Enable signals supplied to each phase cell around the ring are asserted and deasserted in response to state changes in a master clock signal, enable signals supplied to non-adjacent phase cells being provided concurrently. When initialized with one phase cell asserting its phased clock signal and prebias output signal, each transition of the mas­ter clock signal causes a next phase cell on the ring to supply its phased clock output signal.
