NEAR FIELD COMMUNICATION DEVICE, TERMINAL DEVICE HAVING THE SAME, AND OPERATION METHOD OF THE NEAR FIELD COMMUNICATION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17895326 titled 'NEAR FIELD COMMUNICATION DEVICE, TERMINAL DEVICE HAVING THE SAME, AND OPERATION METHOD OF THE NEAR FIELD COMMUNICATION DEVICE
Simplified Explanation
The abstract describes a patent application for a near field communication (NFC) device that includes a phase detector and a phase delay calculator to control the phase of the transmission clock signal applied to the antenna of the reader device.
- The NFC device includes a phase detector that receives a reference clock signal, detects its phase, and outputs a generated clock signal with a synchronized frequency.
- The phase information of the generated clock signal is stored as a first digital code.
- A phase delay calculator compares the phase of the generated clock signal with a reference phase during an active load modulation (ALM) operation and calculates a delta value, which is stored as a second digital code.
- A transmission clock signal generator uses the first and second digital codes to output a transmission clock signal.
- The NFC device controls the phase of the transmission clock signal applied to the reader device's antenna to achieve optimal load modulation amplitude (LMA).
Potential Applications
- Near field communication (NFC) devices in various industries, such as mobile payments, access control systems, and transportation ticketing.
- IoT devices that utilize NFC technology for communication and data transfer.
Problems Solved
- Ensures optimal load modulation amplitude (LMA) by controlling the phase of the transmission clock signal.
- Improves the efficiency and reliability of NFC communication by synchronizing the frequency of the generated clock signal with the reference clock signal.
Benefits
- Enhanced performance and reliability of NFC devices.
- Improved data transfer speed and accuracy.
- Enables seamless and secure communication between NFC devices.
Original Abstract Submitted
A near field communication (NFC) device includes a phase detector for receiving a reference clock signal, detecting a phase of the reference clock signal, outputting a generated clock signal having a frequency synchronized with the reference clock signal, and storing phase information of the generated clock signal as a first digital code. A phase delay calculator compares the phase of the generated clock signal applied from the phase detector and a reference phase to calculate a delta value while performing an active load modulation (ALM) operation and stores the delta value as a second digital code. A transmission clock signal generator reflects phase information stored as the first digital code and the second digital code to output a transmission clock signal. Accordingly, the NFC device controls the phase of the transmission clock signal applied to the antenna of the reader device to have optimal load modulation amplitude (LMA).
