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.

Claim (Index 1):
A phase interpolator device comprising:\n a clock buffer for receiving input clock signals and providing buffered clock signals, the input clock signals including a first clock signal and a second clock signal, the first clock signal and the second clock signal being separated by a predetermined phase, the buffered clock signals including a first buffered clock signal and a second buffered clock signal, a digital-analog-converter (DAC) module comprising DAC blocks and being configured to generate an intermediate clock signal, the DAC blocks including a first DAC block and a second DAC block, the first DAC block being configured to process the first buffered clock signal and contribute to the intermediate clock signal at a first time interval at a first predetermined weight, the second DAC block being configured to process the second buffered clock signal and contribute to the intermediate clock signal at a second time interval at a second predetermined weight, the first time interval partially overlapping the second time interval; and a clock generator configured to generate an output clock signal using at least the intermediate clock signal; wherein the first DAC block is configured to operate in a mixing mode until a predetermined trip point is reached.
