W-Band MMIC Amplifiers Based on AlInN/GaN HEMTs Grown on Silicon

Nicolas Grandjean, Jean-François Carlin, Marco Malinverni, Lorenzo Lugani

We demonstrate W-band monolithic microwave integrated circuit (MMIC) amplifiers based on AlInN/GaN high electron mobility transistors (HEMTs) grown on Silicon. Our MMIC process was fully characterized to 110 GHz and a design kit generated to enable circuit ...

A Time-Based, Digitally Intensive Circuit and System Architecture for Wireless Neural Recording with High Dynamic Range

Alexandre Schmid, Chen Cao, Wen-Yang Hsu

A new type of wireless neural recording front-end with PWM modulation and VCO-based ADC is proposed. The target signal is first encoded into binary levels with varying pulse width by PWM modulation, which intrinsically has much higher dynamic range compare ...

Digital Predistortion of Power Amplifier Non-Linearities for Full-Duplex Transceivers

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Andrew Charles Mallory Austin

Non-linearities introduced by the power amplifier stage can significantly reduce the performance of self-interference cancellation in full-duplex transceivers. Accordingly, we propose a full-duplex system architecture that predistorts the digital baseband ...

The upgraded JET toroidal Alfven eigenmode diagnostic system

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard

The main characteristics of toroidal Alfven eigenmodes (TAEs) have been successfully investigated in JET (Joint European Torus) using the scheme of sweeping-frequency external excitation with tracking of the synchronously-detected resonances. However, due ...
