  • Method and circuit for filtering glitches
    Patent number: 7719320
    Abstract: A circuit for filtering glitches that corrupt a digital input signal includes an enable path input with the digital signal and a reset signal. The enable path generates a corresponding active output signal when the reset signal is null and the digital signal assumes a logic active value, or a null output signal when the reset signal is asserted. The circuit also includes a delay line producing an internal signal as delayed replica of the output signal. The circuit further includes a disable path enabled or disabled by the internal signal, which receives the digital signal and, when enabled, asserts the reset signal when the digital signal becomes null.
