Reversed Feedback Amplifier Architecture

Abstract

Researchers at the University of California, Davis have developed a reversed feedback amplifier design for enhanced mm-wave signal amplification.

Full Description

The technology pertains to the field of mm-wave signal amplification, particularly through the use of reversed feedback amplifiers and cascaded amplifier structures. It addresses the challenges of amplifying signals in the mm-wave frequency bands, crucial for applications like wireless communications and radar systems. The technology overcomes the limitations of traditional amplifiers by employing a unique topology that includes a MOSFET (metal-oxide-semiconductor field-effect transistor) with specific passive components to achieve maximum gain operation and compensate for passive losses.

Applications

• Wireless communication systems, including 5G and beyond. 
• Data center communication circuits for high-speed data transfer. 
• High-resolution imaging for medical and security applications. 
• Advanced radar systems for automotive and aerospace industries. 
• Any application requiring consistent, high-gain operation in mm-wave frequency bands.

Features/Benefits

• Enhanced gain across mm-wave frequency bands, overcoming the limitations of dissipative losses. 
• Improved bandwidth through stagger tuning and cascading multiple amplifier stages without the need for matching networks. 
• Optimized for high-gain, broadband operation, essential for advanced communication and radar systems. 
• Reduction in chip area and DC power consumption compared to traditional cascading techniques. 
• Capability to overcome passive losses and achieve maximum gain (Gmax) operation.
