  • Patent number: 6405228
    Abstract: A circuit comprising a filter circuit and a delay circuit is disclosed. The filter circuit may be configured to present an output signal in response to (i) an input signal having one or more glitches and (ii) a control signal having a plurality of transitions between a first and a second state. The delay circuit may be configured to generate the control signal such that the output signal is generated without glitches. In one example the delay circuit may dynamically adjust the control signal in response to a period of the input signal.

  • Patent number: 6137333
    Abstract: A first detection circuit, a second detection circuit and a counter circuit. The first detection circuit may be configured to present a first control signal in response to (i) an input signal having a period, (ii) an output signal and (iii) an enable signal. The second detection circuit may be configured to present a second control signal in response to (i) the input signal, (ii) the output signal and (iii) the enable signal. The counter circuit may be configured to present a delay signal in response to (i) the first control signal, (ii) the second control signal and (iii) the output signal. The delay signal may be a fraction of the period of the input signal.
