    摘要: A circuit includes a first delay filter, a first comparator, an inverter, a second delay filter, a second comparator, an OR gate, and a latch. A first delay filter input is coupled to an inverter input. The first comparator has a first comparator input coupled to a first delay filter output and a second comparator input. The second delay filter has an input coupled to an inverter output. The second comparator has a third comparator input coupled to a second delay filter output, and a fourth comparator input coupled to the second comparator input. The OR gate has an input coupled to a first comparator output and another input coupled to a second comparator output. The latch has a clock input coupled to an OR gate output and a latch input coupled to the inverter input. A latch output provides a deglitched signal.

    摘要: In at least some examples, an integrated circuit includes an input pin and an analog-to-digital converter (ADC) comprising an input terminal coupled to the input pin and an output terminal. The integrated circuit further includes a logic circuit comprising an input terminal coupled to the output terminal of the ADC, a first output terminal, and a second output terminal. The integrated circuit further includes a resistance circuit. In an example, the resistance circuit includes a resistor coupled between the input pin and a first node, a first switch coupled between the first node and a reference voltage pin, and a second switch coupled between the first node and a ground pin.
