    摘要: A circuit includes a frequency synthesizer, N phase mixers coupled to the frequency synthesizer, a plurality of receivers, and a calibration circuit. The frequency synthesizer is to receive a reference clock signal and is to output a primary clock signal. A respective phase mixer in the N phase mixers is to output a respective secondary clock signal having a corresponding phase. A respective receiver in the plurality of receivers is coupled to two of the N phase mixers, and at a respective time is to receive data in accordance with the respective secondary clock signal from one of the two phase mixers coupled to the respective receiver. The calibration circuit is to calibrate a secondary clock signal output by a respective phase mixer in the N phase mixers by adjusting the phase of the secondary clock signal of the respective phase mixer.

    摘要: In raised source/drain CMOS processing, the prior art problem of lateral epi growth on the gate stack interfering physically with the raised S/D structures and producing device characteristics that vary along the length of the gate and the problem of overetch of the STI oxide during the preclean step is solved by using a sacrificial nitride layer to block both the STI region and the gate stack, together with a process sequence in which the halo and extension implants are performed after the S/D implant anneal.

    摘要: A circuit includes a phase interpolator and a self test circuit. The phase interpolator is to provide a interpolator output having a phase corresponding to a respective phase step in a plurality of phase steps. The interpolator output is a weighted combination of one or more of a plurality of phasor signals. The self test circuit includes a phase detector coupled to a reference signal and the interpolator output, a phase-difference-to-voltage converter coupled to the phase detector, an analog-to-digital converter (ADC) coupled to the phase-difference-to-voltage converter, and control logic. The phase detector is to generate an output that is proportional to a phase difference between the reference signal and the interpolator output. The phase-difference-to-voltage converter is to convert the output from the phase detector into a corresponding voltage. The ADC is to convert an output from the phase-difference-to-voltage converter into a corresponding digital value. The control logic is to test the phase interpolator using the self-test circuit.
