Abstract: The present invention relates generally to integrated circuits. More particularly, the present invention provides a circuit and method for a CMOS interpolator for an output clock signal with a desirable phase for a high speed serializer/deserializer device. In a specific embodiment, the present invention provides a phase interpolator device that mixes phase-shifted clock signals according to a predetermined weight values at predetermined time intervals. There are other embodiments as well.

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: This disclosure relates to the field of amplifiers for multi-level optical communication and more particularly to techniques for trans-impedance amplifiers (TIA) with gain control. The claimed embodiments address the problem of implementing a low cost TIA that exhibits high linearity, low noise, low power, and wide bandwidth. More specifically, some claims are directed to approaches for providing TIA gain control using a plurality of inverter-based replica gain control cells controlled by a feedback loop to manage the current into the amplifying output stage and thereby the TIA output voltage.
