  • Publication number: 20220200781
    Abstract: A quadrature clock generator that takes advantage of the inherently low delay of a shunt-series inductively peaked clock buffer to generate quadrature clocks with the high jitter performance using just one additional stage in Q path compared to I path. The generator includes a delay cell that uses shunt-series peaking and uses a resistive DAC in series with the shunt inductor to provide a large delay range with good jitter characteristics. The resistive DAC can be placed near a real or a virtual ground to minimize capacitive loading on the signal path. This delay cell can provide greater than 2× delay tuning range and is suitable for clocks at high frequencies. This delay cell can also be used as a ring oscillator with large frequency tuning range. A low voltage differential signaling termination switch control that uses feed forward mechanism to control termination impedance of device in a receiver.

  • Publication number: 20220171718
    Abstract: A clock buffer that uses low-to-medium quality factor (e.g., QF of 2 to 5) inductors in shunt-series and in series-shunt configuration in high-speed clock distribution stages. Shunt-series and series-shunt inductors extend amplifier bandwidth. Applying shunt-series and series-shunt inductors to high-speed clock distribution filters jitter, attenuates supply noise, and improves fanout. An asymmetric multiplexer with inductors in shunt or in shunt-series configurations. Another asymmetric multiplexer with capacitively coupled tri-stateable inverter-based buffer stages. These two multiplexer techniques along with the ability to ‘hide’ a load of a non-preferred path at a virtual ground node of the shunt inductor, the multiplexer improves the jitter and power consumption of the preferred path significantly. A de-multiplexer (DeMux) is also shown using inductors. A combination of a shunt-multiplexer and an inductor-based DeMux is also discussed.
