HIGH RESOLUTION PHASE CORRECTING CIRCUIT AND PHASE INTERPOLATING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17872527 titled 'HIGH RESOLUTION PHASE CORRECTING CIRCUIT AND PHASE INTERPOLATING DEVICE
Simplified Explanation
The patent application describes a phase correcting circuit that can adjust the timing of an output clock signal. The circuit includes a delay circuit, a first fine tuning circuit, and a second fine tuning circuit.
- The delay circuit receives an input clock signal and delays it by a certain amount of time to generate an output clock signal.
- The first fine tuning circuit is connected to the output of the delay circuit and has three terminals. It can further delay the output clock signal based on a first control signal.
- The second fine tuning circuit is connected to the third terminal of the first fine tuning circuit and has three terminals. It can advance the output clock signal based on a second control signal.
- The second delay time, controlled by the first fine tuning circuit, is shorter than the first delay time.
- The third delay time, controlled by the second fine tuning circuit, is also shorter than the first delay time.
Potential applications of this technology:
- This phase correcting circuit can be used in various electronic devices that require precise timing, such as communication systems, data transmission systems, and digital signal processing.
- It can be particularly useful in high-speed data communication where accurate synchronization is crucial.
Problems solved by this technology:
- The phase correcting circuit addresses the issue of timing misalignment in electronic systems by allowing fine adjustments to the output clock signal.
- It provides a solution for compensating for delays or advances in the signal propagation, ensuring accurate timing synchronization.
Benefits of this technology:
- The circuit allows for precise control over the timing of the output clock signal, improving the overall performance and reliability of electronic systems.
- It offers flexibility in adjusting the timing, allowing for optimization based on specific requirements or environmental conditions.
- The phase correcting circuit can be easily integrated into existing electronic systems, providing a cost-effective solution for improving timing accuracy.
Original Abstract Submitted
A phase correcting circuit includes a delay circuit that receives an input clock signal and delays the input clock signal as much as a first delay time to output an output clock signal to a 0-th node, a first fine tuning circuit, and a second fine tuning circuit. The first fine tuning circuit includes a first terminal connected with the 0-th node, a second terminal receiving a first control signal, and a third terminal, and the second fine tuning circuit includes a fourth terminal connected with the third terminal, a fifth terminal receiving a second control signal, and a sixth terminal connected with a load capacitor. In response to the first control signal, the output clock signal may be further delayed as much as a second delay time shorter than the first delay time. In response to the second control signal, the output clock signal may be advanced as much as a third delay time shorter than the first delay time.
