Abstract: The present invention relates to telecommunication techniques and integrated circuit (IC) devices. In a specific embodiment, the present invention provides a laser deriver apparatus that includes a main DAC section and a mini DAC section. The main DAC section processes input signal received from a pre-driver array and generates an intermediate output signal. The mini DAC section provides a compensation signal to reduce distortion of the intermediate output signal. The intermediate output signal is coupled to output terminals through a cascode section and/or a T-coil section. There are other embodiments as well.

Abstract: The present invention relates to data communication techniques and integrated circuit devices. More specifically, embodiments of the present invention provide an input buffer module that utilizes one or more equalization elements. The input buffer module includes an array of inverters arranged in a series. An equalization element is configured in series relative to a segment of the array of inverters. The resistance value of the equalization element is predetermined based on a delay associated with the segment of the array of inverters. There are other embodiments as well.
