SEMICONDUCTOR DEVICE AND COMMUNICATION DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17881734 titled 'SEMICONDUCTOR DEVICE AND COMMUNICATION DEVICE INCLUDING THE SAME

Simplified Explanation

The patent application describes a semiconductor device that includes various circuits to amplify input signals, perform feedforward control, and provide common-mode feedback.

• The device includes a first amplifier that amplifies two input signals and outputs two amplified signals.
• A second amplifier receives and amplifies the first amplified signals and outputs two output signals.
• A feedforward circuit receives the input signals and performs feedforward control on the output signals.
• A common-mode feedback circuit receives the output signals and adjusts their average to match a reference signal.
• The common-mode feedback circuit supplies the feedback signal to the first amplifier and the feedforward circuit.

Potential applications of this technology:

• Audio amplifiers
• Communication systems
• Signal processing devices

Problems solved by this technology:

• Maintains a stable and accurate average output signal by adjusting for common-mode variations.
• Provides feedforward control to improve the performance and stability of the output signals.

Benefits of this technology:

• Improved signal amplification and accuracy.
• Enhanced stability and performance of the output signals.
• Efficient common-mode feedback control.
