  • Patent number: 8395430
    Abstract: The present disclosure discloses a digital phase locking loop and a method. The digital phase locking loop includes a trigger and a delay line. The trigger receives a delayed clock signal output by the delay line, and receives a signal of a selection end of a first delay element in the delay line; the selection end is in a gating state before triggering of the trigger. The trigger samples the signal of the selection end of the first delay element, and outputs the sampled signal to a selection end of a second delay element in the delay line; the selection end of the second delay element is in the gating state after triggering of the trigger. The signal of the selection end of the first delay element is sampled by the trigger, and the sampled result is used as the signal of the selection end of the second delay element, thus reducing glitches caused by transition.

  • Patent number: 7622702
    Abstract: The invention discloses a power controlling apparatus for a biochip including M regions. Each region includes a plurality of cells respectively. The power controlling apparatus includes a pulse generating module, a combinational circuit, and M controlling modules. The pulse generating module generates a pulse. The combinational circuit receives the pulse and generates M controlling signals. Each controlling signal has a predetermined phase which is different from the phase of the other controlling signal. The M controlling modules are electrically connected to the combinational circuit. Each of the M controlling signals corresponds to and activates one of the M controlling modules to selectively power on one corresponding region of the M regions. The cells in the corresponding region which is powered have an action potential refractory time that is longer than the power-on interval of the corresponding region.
