Introduction

Bhupendra K Ahuja is a notable inventor based in Fremont, California, with a remarkable portfolio of nine patents. His work primarily focuses on advancements in phase-locked loops and real-time clock chips, showcasing his expertise in electronic engineering and innovation.

Latest Patents

One of his latest patents is titled "Method and system for quantization-free and phase-dithered fractional-N generation for phase-locked-loops." This invention includes a phased lock loop (PLL) that features a retimer unit, a rotator unit, and a clock selection unit. The retimer unit samples a divided clock generated by a divide-by-N unit with multiple phases of an oscillator clock produced by a ring oscillator. This process generates several phase-shifted divide-by-N clocks. The rotator unit selectively rotates through these clocks based on a constant phase shift interval, controlling the clock selection unit to produce a single output phase from the generated divide-by-N clock phases.

Another significant patent is the "Automatic circuit and method for temperature compensation of oscillator frequency variation over temperature for a real-time clock chip." This invention involves an automatic temperature compensated real-time clock (RTC) chip that includes a crystal oscillator block with crystal compensation circuitry. The circuitry is designed to be coupled to a crystal and features a non-linear capacitor DAC with multiple load capacitors. These capacitors have switches that adjust the parallel resonance frequency generated by the oscillator block. The system also includes a temperature sensor block that measures the crystal's temperature, allowing for precise frequency correction.
