LINEARITY ENHANCEMENT FOR DIGITAL WIRELESS TRANSMITTERS AND DIGITAL POWER AMPLIFIERS

VAlue proposition

Digital transmitters and digital power amplifiers are an active area with the advance of CMOS technology. Energy-efficient transmitters are critical for many applications that employ MIMO, multiband, and multi-standard transceivers because of multiple transmitters being adopted in a single chip or system. A very linear transmitter with wide bandwidth is also desired as is reduced chip area and high data throughput. This technology offers a comprehensive solution for enhancing the performance of digital wireless transmitters. It addresses key challenges such as energy efficiency, linearity, and bandwidth, making it a valuable advancement for the development of next-generation wireless communication systems.

Description of Technology

The technology described is a method for correcting phase distortion in a digital wireless transmitter. This technique involves several steps. The process begins with the reception of a Radio Frequency (RF) signal in the analog domain. This is achieved through a digital-to-RF modulator, which converts digital data into an RF signal. The received RF signal is then amplitude modulated in accordance with a digital input code. The next step involves introducing a delay in the signal path traversed by the RF signal. The duration of this delay is determined by the value of the digital input code. The purpose of this delay is to substantially cancel out the phase distortion that may have been introduced by the digital wireless transmitter. The primary application of this technology is in digital wireless communication systems where phase distortion can affect the quality and reliability of the transmitted data. By correcting this distortion, the system can maintain higher data integrity and improve overall performance. The specific areas of applicability may vary depending on the exact implementation and design of the digital wireless transmitter system.
