TRANSMITTER CIRCUIT AND OPERATION METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18189521 titled 'TRANSMITTER CIRCUIT AND OPERATION METHOD THEREOF

Simplified Explanation

The abstract describes a transmitter circuit that includes an impedance calibration circuit, an encoder, a delay circuit, and a feed-forward equalizer. Here is a simplified explanation of the patent application:

• The transmitter circuit is designed to match the impedance of the transmission line.
• An impedance calibration circuit generates an impedance code to achieve impedance matching.
• An encoder receives the impedance code and generates a delay compensation signal based on it.
• A delay circuit outputs delayed data based on the delay compensation signal.
• A feed-forward equalizer receives the input data and the delayed data.
• The feed-forward equalizer equalizes the input data using main and equalization coefficients.
• The equalized data is then transmitted.

Potential applications of this technology:

• This technology can be used in wireless communication systems, such as cellular networks, to improve signal transmission quality.
• It can also be applied in satellite communication systems to enhance data transmission efficiency.
• The transmitter circuit can be used in various types of transmitters, including radio transmitters and television transmitters.

Problems solved by this technology:

• Impedance mismatch can cause signal reflections and reduce the overall performance of a transmission system. This technology solves this problem by providing an impedance calibration circuit.
• Delay in signal transmission can lead to distortion and errors. The delay compensation signal and delay circuit address this issue by synchronizing the data transmission.

Benefits of this technology:

• The impedance calibration circuit ensures optimal impedance matching, resulting in improved signal quality and reduced signal loss.
• The delay compensation signal and delay circuit help in synchronizing the data transmission, minimizing distortion and errors.
• The feed-forward equalizer enhances the quality of the transmitted data by compensating for channel impairments.

Original Abstract Submitted

In a transmitter circuit, an impedance calibration circuit is configured to generate an impedance code for impedance matching, an encoder is configured to receive the impedance code and to generate a delay compensation signal based on the impedance code. A delay circuit is configured to output delay data that are delayed from input data by a delay value determined based on the delay compensation signal. A feed-forward equalizer is configured to receive the input data and the delay data, and to equalize the input data based on a main coefficient used for the input data and an equalization coefficient used for the delay data to generate transmission data.
