Techniques are described herein that adaptively suppress harmonic distortion in an amplifier utilizing negative gain. The amplifier includes a first amplifier stage and a second amplifier stage, which are coupled in parallel. The first amplifier stage has a positive gain. The second amplifier stage has a negative gain to suppress total harmonic distortion of a system that includes the amplifier. The amplifier further includes shunt-peaking circuitry coupled to the first amplifier stage and the second amplifier stage to increase a maximum operating frequency at which the amplifier is capable of operating.

Adaptive harmonic distortion suppression in an amplifier utilizing negative gain

A communication system may include a number of communication channels operating in accordance with one or more communication standards. The channels may generate data clocks from one or more master clock signals. The phase of the data clocks may be aligned using phase detectors for determining respective phase relationships and using phase interpolators for adjusting respective clock phases. The communication system may include communication channels that operate at different data clock frequencies. These systems may divide their respective data clocks in order to achieve a common clock frequency for use in their phase alignment. The phase detectors and associated circuitry may be disabled to save power when not in use.
