Latest Patents
Rieder's latest patents include innovative solutions for synchronized clocks and clock generators. One of his patents describes a synchronized clock using a non-pullable reference oscillator. This invention utilizes digital signal processing techniques to synthesize a range of output frequencies locked to a non-pullable reference oscillator. The synthesized output frequency is employed in a slave low bandwidth phase-locked loop. By enhancing digital resolution in a phase accumulation register, any desired resolution of output frequencies can be generated. The design ensures that only high-frequency jitter is produced, which can be effectively filtered by subsequent low-cost, high-bandwidth phase-locked loops necessary for frequency multiplication in various systems.
Another significant patent outlines a circuit arrangement for a clock generator. This invention addresses the stringent requirements for accuracy and stability in clock generators, which are essential for error-free digital information transmission. Rieder's design features microprocessor-controlled digital phase-locked loops that can maintain an accurate system clock signal even in the event of a reference clock signal failure. The invention cleverly divides the contradictory requirements placed on phase-locked loops between two loops, ensuring high accuracy and minimal jitter.
