Latest Patents

Fengqi Zhang holds a patent for a Phase Rotator Apparatus. This apparatus features phase interpolation and transimpedance amplifier (TIA) stages. The design separates gain and bandwidth as degrees of design freedom, which facilitates a reduction in power consumption while enabling the data link to transmit and receive higher speed data. The phase interpolation stage combines four phases of an incoming signal using weighting currents and current-source loads. This process produces a phase-shifted current-based signal that the TIA stage receives as input. The TIA stage then converts this signal into a voltage-based signal. Additionally, the quiescent operating voltage of the stage outputs can be maintained with common mode feedback circuits and injector currents.
