    摘要: An output driver for enhancing initial output data using timing includes a selection signal generation unit for generating a selection signal, a reference data generation unit for generating reference data, and a selection unit. The selection signal is activated at the transition point of the input data, generated after being maintained in a same logic state during a number of bit periods that is equal to or greater than a predetermined duration number. The reference data is delayed from the input data by a delay time shorter than one bit period. The selection unit is driven to transition the logic state of the output data depending on the transition of the logic state of any one of the input data and the reference data in response to the selection signal.

    摘要: In a decision feedback equalization (DFE) input buffer, timing and voltage errors, such as those caused by inter-symbol interference (ISI), are fully compensated. A variable equalizing coefficient is applied that accommodates, and compensates for, a range of timing errors TE or voltage errors VE that may be generated over a range of operating conditions. In this manner, accurate compensation is achieved, allowing for greater signal reliability and higher inter-circuit transfer rates. A decision feedback equalization (DFE) input buffer includes an equalizer that amplifies a difference in voltage level between an input signal and an oversampled signal in response to a variable equalizing control signal, the equalizer generating an amplified output signal. A sampling unit samples the amplified output signal in response to a sampling clock signal to generate the oversampled signal. A phase detector generates a timing control signal for controlling the timing of the activation of the sampling clock signal in response to a phase of the oversampled signal. An equalizing controller modifies the variable equalizing control signal in response to the timing control signal.
