Offer Description

ENSEA is a leading French Graduate School of Engineering in the field of digital technologies, awarding engineering degrees since 1952. ENSEA also hosts nine research teams grouped into two internationally renowned laboratories: LEA (Electronics and Automation Laboratory) and ETIS, a CNRS joint research unit specializing in information processing and systems.

The aim of this PhD thesis is to design and characterize a low-noise amplifier operating at the quantum limit in the W-band (75–110 GHz). The monolithic amplifier will integrate a superconducting first stage based on the inelastic tunneling effect of Cooper pairs, followed by subsequent stages using HEMT transistors. The targets include achieving an input noise level as low as allowed by the laws of quantum mechanics—equivalent to 1 photon—which at 100 GHz corresponds to a noise temperature of approximately 5 K, or a noise figure of 0.07 dB.

The amplifier should provide a gain of approximately 30 dB while consuming less than 25 mW in order to operate at cryogenic temperatures.

Missions:

• Design of high-speed integrated electronic circuits
• Design of high-speed electronic systems
