Filed: 2000-03-07
Abstract: PURPOSE: A method and circuits for immunization against noise inherent in signal level transition are provided to obtain an output signal immunized against noise during signal transition and select state transition points away from noise range. CONSTITUTION: A circuit for immunization against noise inherent in signal level transition comprises a first circuit(11) for supplying a first transient signal and a second transient signal, and a second circuit(21) for detecting an input signal to supply an output signal. The states of the first and the second transient signals are determined by a first transition threshold and a second transition threshold, respectively. Both of the first and the second transition thresholds are outside noise range. When the input signal decreases from a level to the first transition threshold, the output signal of a first output state is supplied in response to the first transient signal. When the input signal increases from a level to the second transition threshold, the output signal of a second output state is supplied in response to the second transient signal.
