An electronic circuit may include a driver, a delay circuit, a strength control circuit, and an adder circuit. The driver may generate a second signal based on a first signal. The delay circuit may delay the first signal by as much as a reference time, to generate a third signal. The strength control circuit may adjust an amplitude of the third signal to generate a fourth signal. The adder circuit may add the second signal and the fourth signal to generate a fifth signal. In a first time interval determined based on the reference time, an amplitude of the fifth signal may be greater than an amplitude of the second signal. In a second time interval except for the first time interval, the amplitude of the fifth signal may be smaller than the amplitude of the second signal. In the second time interval, the amplitude of the fifth signal may be smaller than an amplitude of the first signal.
