Input apparatus and input system

摘要

An input apparatus may include a pulse width control circuit, a reception circuit, and a latch circuit. The pulse width control circuit may be configured to generate a pulse width control signal by performing a logical operation on a pulse width detection signal and a clock signal. The reception circuit may be configured to selectively provide a received input signal as a period signal on the basis of the clock signal and the pulse width control signal. The latch circuit may be configured to provide an output signal by inverting the period signal, and provide the output signal as the pulse width detection signal in response to the clock signal.

1. An input apparatus comprising:
a pulse width control circuit configured to generate a pulse width control signal by performing a logical operation on a pulse width detection signal and a clock signal; a reception circuit configured to selectively provide a received input signal as a period signal based on the clock signal and the pulse width control signal; and a latch circuit configured to provide an output signal by inverting the period signal, and provide the output signal as the pulse width detection signal in response to the clock signal, wherein the reception circuit further includes:
a path blocking circuit configured to block a path wherein the input signal is inverted so that the inverted resultant signal is provided as the period signal in response to an inverted pulse width detection signal corresponding to inversion of the pulse width detection signal.
