In some embodiments, a differential amplifier with duty cycle correction is provided.

Forwarded clock jitter reduction

Described herein are an apparatus, system, and method for compensating voltage swing and duty cycle of a signal on an input-output (I/O) pad of a processor by adjusting the voltage swing and duty cycle of the signal. The apparatus comprises a driver to transmit a signal on an I/O pad, the signal on the I/O pad having a voltage swing and a duty cycle; and an adjustment unit, coupled to the driver, to receive the signal from the I/O pad transmitted by the driver and to generate voltage swing and duty cycle control signals for adjusting the voltage swing and duty cycle of the signal on the I/O pad respectively. Described herein is also an analog-to-digital (A2D) converter for measuring and/or calibrating various signal attributes including current, voltage, and time.

Apparatus, system, and method for voltage swing and duty cycle adjustment

A transmitter architecture includes an equalizer and a D/A converter, for high-speed transmission of data across a channel. The equalizer includes a two-tap MAC as part of an N-stage, two-way interleaved FIR filter. The two-tap MAC provides substantial power and area savings over conventional MAC-based FIR filter designs, and may be implemented in short or long communications channels. The D/A converter is decoupled from the equalizer. Its N-bit, binary-weighted driver includes matched unit current generation cells, all of which are fully utilized during each digital-to-analog conversion. The D/A converter remains unchanged, even when the characteristics of the equalizer are changed.

Transmitter architecture for high-speed communications

An apparatus for controllably distorting the duty cycle of a clock signal is disclosed. Methods and systems using embodiments of the invention are also described.
