Abstract: In an example, the present invention provides an analog to digital converter device for a high speed data transmission from 1 GS-s to 100 GS-s, although there can be other variations. In an example, the device has an input receiver device coupled to a transimpedance amplifier. In an example, the transimpedance amplifier is coupled to an input stream of data at 10 GHz to 100 GHz, or other variations.

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 is directed integrated circuits and methods thereof. More specifically, an embodiment of the present invention provides a comparator calibration loop where a digital integrator stores a running sum based on the output of a comparator. A DAC converts the running sum and generates an offset calibration voltage, which is filtered by a low-pass filter module, and the filtered offset calibration voltage is used to cancel out the intrinsic offset voltage and low frequency noise of the comparator. There are other embodiments as well.
