Abstract
A signal generation circuit includes a synchronization circuit, a pulse width control circuit, and an output circuit. The synchronization circuit synchronizes an input signal with a clock signal to generate a synchronization signal. The pulse width control circuit generates a start signal from the synchronization signal and generate an end signal by delaying the synchronization signal by a time corresponding to an off control signal in synchronization with the clock signal. The output circuit generates an output signal based on the start signal and the end signal.
Claims17
A signal generation circuit comprising:
- a synchronization circuit configured to synchronize an input signal with a clock signal to generate a synchronization signal;
- a pulse width control circuit configured to delay the synchronization signal to generate a start signal, and delay the synchronization signal by a time corresponding to an off control signal in synchronization with the clock signal to generate an end signal;
- and
- an output circuit configured to enable an output signal based on the start signal and disable the output signal based on the end signal.
A signal generation circuit comprising:
- a synchronization circuit configured to synchronize an input signal with a clock signal to generate a synchronization signal, whenever the input signal is inputted;
- a pulse width control circuit configured to delay the synchronization signal to generate a start signal, and delay the synchronization signal by a time corresponding to an off control signal in synchronization with the clock signal to generate an end signal;
- and
- an output circuit configured to enable an output signal based on a start signal which does not overlap the end signal, and disable the output signal based on an end signal which does not overlap the start signal.
