Input circuit with switched reference signals |
摘要 |
An input circuit includes a comparator circuit and a multi-reference circuit. The input circuit receives an input signal and generates an output signal as a function of the input signal and a reference signal received from the multi-reference circuit. The comparator circuit detects a crossing of the input signal relative to the reference signal and causes a corresponding transition of the output signal. In response to the transition of the output signal, the multi-reference circuit provides a different reference signal to the comparator circuit. The reference signals provided by the multi-reference circuit are selected to create hysteresis in the operation of the input circuit.
