Latest Patents

One of Hemesh's latest patents is titled "Oscillator amplitude calibration." This invention allows for the selection of multiple voltage amplitudes for an oscillator in a phase-locked loop to meet various design goals, such as frequency range of operation, jitter, and power consumption. The multiple voltage amplitudes are stored in a lookup table memory that relates frequency ranges to reference voltages. A feedback loop compares the amplitude output by the oscillator to the reference voltage and adjusts a bias current to equalize the oscillator output to the reference voltage.

Another significant patent is the "Low jitter clock multiplier circuit and method with arbitrary frequency acquisition." This invention describes a circuit and method for generating a low jitter output clock with an arbitrary non-integer divide ratio relative to a high-frequency clock. The method allows for flexibility in clock generation, enabling the use of high-frequency clocks that are not constrained by integer multiples of desired output clock signals.
