Jitter Compensation Circuit for IC Voltage Stability

The patent divides the single large capacitor solution into multiple smaller capacitors (first capacitor and second capacitor) that operate at different stages. The first capacitor is coupled to the output of the voltage regulator, and the second capacitor is coupled to the output of the jitter compensation circuit, creating a segmented filtering approach that reduces individual capacitor size requirements while maintaining overall voltage stability.

The patent introduces a jitter compensation circuit as an intermediary component between the voltage regulator and the load. This circuit includes transistors (first transistor, second transistor, third transistor) and control circuits that actively compensate for voltage fluctuations caused by jitter, thereby reducing the burden on passive capacitors and enabling the use of smaller, more cost-effective capacitance values.

The patent replaces the expensive large capacitor solution with a combination of smaller, cheaper capacitors and active circuit components. The jitter compensation circuit uses standard-value capacitors (first capacitor and second capacitor) that are less costly than a single large capacitor would be, while the active transistor-based compensation provides the necessary reliability for data transmission.

The patent creates a composite solution combining multiple components (voltage regulator, first capacitor, second capacitor, jitter compensation circuit with transistors) to achieve the reliability of a large capacitor system. This composite approach distributes the functionality across multiple smaller, cheaper components rather than relying on a single expensive component.
