    Abstract: An electronic device includes a first duty cycle correction circuit, a delay line, a second duty cycle correction circuit, and a delay control circuit. The first duty cycle correction circuit is configured to detect a duty cycle error of a clock signal by performing time-to-digital conversion on the clock signal, and to generate a corrected clock signal by adjusting a duty cycle of the clock signal based on the duty cycle error of the clock signal. The delay line is configured to generate a delayed corrected clock signal by delaying the corrected clock signal based on a delay control code The second duty cycle correction circuit is configured to detect a duty cycle error of a first output clock signal received through a feedback loop, and to generate a second output clock signal by adjusting duty cycle of the delayed corrected clock signal based on the duty cycle error of the first output clock signal. The delay control circuit is configured to generate the delay control code based on the clock signal and the first output clock signal.

    Abstract: In a duty cycle error detection device, a first digital code generator is configured to generate high and low codes corresponding to a lengths of high level low level periods, respectively, of a clock signal, generate a sign signal representing the longer period between the high level period and the low level period, and output one of the high and low digital codes corresponding to the shorter period as a first digital code. A clock delay circuit is configured to generate a delay clock signal by delaying the clock signal for a time corresponding to the first digital code, and a second digital code generator is configured to generate a duty error digital code corresponding to a length from a start of the longer period of the delay clock signal to an end of the longer period of the clock signal based on the sign signal.

    Abstract: An input buffer includes a first buffer, a feedback circuit and a second buffer circuit. The feedback circuit includes a feedback resistor and a feedback inverter. The first buffer may be configured to output an amplification signal to an output node of the first buffer based on an input signal. The feedback circuit connected to the output node of the first buffer may be configured to control the amplification signal. The second buffer circuit may be configured to output a buffer output signal by buffering the amplification signal. The feedback resistor may receive the amplification signal from the output node of the first buffer and provide a feedback signal to a feedback node. The feedback inverter is connected between the feedback node and the output node. The feedback inverter may be configured to control the amplification signal based on the feedback signal.
