RECEIVER INCLUDING A PULSE AMPLITUDE MODULATION DECODER, AND A MEMORY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240259007 titled 'RECEIVER INCLUDING A PULSE AMPLITUDE MODULATION DECODER, AND A MEMORY DEVICE INCLUDING THE SAME

The abstract describes a 4-level pulse amplitude modulation (PAM-4) decoder that includes a comparator, a clock delay circuit, and a time-windowed least significant bit (LSB) decoder.

  • The comparator receives first and second input data along with a clock signal, producing comparison results for the input data.
  • The clock delay circuit delays the clock signal to generate a delayed clock signal.
  • The time-windowed LSB decoder receives the comparison data and the delayed clock signal, performing decoding when the delayed clock signal is at a specific level.

Potential Applications: - Communication systems - Data transmission technologies - Signal processing applications

Problems Solved: - Efficient decoding of PAM-4 signals - Improved data transmission accuracy - Enhanced signal processing capabilities

Benefits: - Increased data transmission speeds - Enhanced signal reliability - Improved overall system performance

Commercial Applications: Title: Advanced Signal Processing Technology for High-Speed Communication Systems This technology can be used in telecommunications, networking equipment, and data centers to improve data transmission speeds and accuracy, leading to more efficient and reliable communication systems.

Questions about the technology: 1. How does the delayed clock signal impact the decoding process in the time-windowed LSB decoder? 2. What are the key advantages of using a 4-level PAM-4 decoder in communication systems?


Original Abstract Submitted

a 4-level pulse amplitude modulation (pam-4) decoder including: a comparator configured to receive first input data, second input data, and a clock signal and output first comparison data and second comparison data, wherein the first comparison data and the second comparison data are comparison results for the first input data and the second input data; a clock delay circuit configured to delay the clock signal and generate a delayed clock signal; and a time-windowed least significant bit (lsb) decoder configured to receive the first comparison data, the second comparison data, and the delayed clock signal, wherein the time-windowed lsb decoder is configured to perform a decoding when the delayed clock signal is at a first level.
