  • Patent number: 10476516
    Abstract: A pre-driver circuit includes a differential input circuit to receive a differential-input voltage. A latch circuit can latch voltage levels of output-voltage signals at a differential output port of the pre-driver circuit. A pair of capacitors couple the differential input circuit to the latch circuit. The pre-driver circuit can enable peaking of the output-voltage signals for high-speed operation of the pre-driver circuit and a digital-to-analog converter (DAC)-driver circuit coupled to the pre-driver circuit.

  • Patent number: 10014877
    Abstract: A digital-to-analog converter (DAC) includes a plurality of segments, wherein the plurality of segments includes a first segment electronically coupled to each of the plurality of segments, wherein the first segment includes a predetermined number of most significant bits (MSB), a second segment electronically coupled to each of the plurality of segments, wherein the second segment includes a first predetermined number of least significant bits (LSB), and a third segment electronically coupled with each of the plurality of segments, wherein the third segment includes a second predetermined number of LSBs. Additionally, the DAC includes an all logic implementation.

  • Patent number: 9344268
    Abstract: A phase alignment architecture enhances the performance of communication systems. The architecture aligns a divided clock (e.g., in differential Inphase (I) and Quadrature (Q)) to a main clock, even at extremely high speeds, where skew variations of the divided clock are comparable to the main clock period. The improvement in phase alignment facilitates ultra high-speed communications.

  • Patent number: 9246670
    Abstract: A high-speed clock generator device includes a phase-interpolator (PI) circuit, a smoothing block, and inverter-based low-pass filters. The PI circuit receives a multiple clock signals with different phase angles and generates an output clock signal having a correct phase angle. The smoothing block smooths the clock signals with different phase angles and generates a number of smooth clock signals featuring improved linearity. The inverter-based low-pass filters filter harmonics of the clock signals with different phase angles.

  • Patent number: 9001869
    Abstract: A device for high-speed clock generation may include an injection locking-ring oscillator (ILRO) configured to receive one or more input clock signals and to generate multiple clock signals with different equally spaced phase angles. A phase-interpolator (PI) circuit may be configured to receive the multiple coarse spaced clock signals and to generate an output clock signal having a correct phase angle. The PI circuit may include a smoothing block that may be configured to smooth the multiple clock signals with different phase angles and to generate multiple smooth clock signals. A pulling block may be configured to pull edges of the multiple smooth clock signals closer to one another.

  • Patent number: 8618835
    Abstract: An apparatus is disclosed for converting signals from one digital integrated circuit family to be compatible with another digital integrated circuit family. The apparatus includes a primary interface and a secondary interface to convert a differential output signal from one digital integrated circuit family for use as an input signal by another digital integrated circuit family. The primary and secondary interfaces include gain stages that are configurable to provide rail to rail voltage swings and are characterized as having single pole architectures. The secondary interface may be unterminated such that a substantially equal load is presented to both components of the differential output signal.
