Application: Delay-locked loop circuit and method (Patent ID: US20240106425A1)
The patent filed by Taiwan Semiconductor Manufacturing Co Ltd describes a delay-locked loop (DLL) circuit that includes a low pass filter, a phase detector, and a digitally controlled delay line (DCDL) with multiple stages. Each stage of the DCDL includes inverters that selectively propagate signals along different paths, allowing for precise control over signal delays. The DCDL is designed to synchronize clock signals by selecting a return stage based on a detected phase difference, with the ability to activate specific inverters in each stage to achieve the desired delay.
The method outlined in the patent involves receiving clock signals, detecting phase differences, and using a control circuit to select the appropriate return stage in the DCDL for signal synchronization. By activating specific inverters in each stage, the method allows for fine-tuning of signal delays to ensure accurate synchronization. The patent highlights the tunable nature of the inverters in the DCDL stages, providing flexibility in adjusting signal paths for optimal performance.
