Phd position on cryogenic low-noise low-power sub-10ghz receivers

Cryogenic low-noise low-power sub-10GHz receivers.

In this Ph.D. Research, we will focus on the development of cryogenic CMOS receivers with 4K noise temperature. We will first investigate the essential functionalities required to read out the multiple resonators and compare different readout architectures based on their potential in scalability, intrinsic signal-to-noise ratio, and shortest readout time. Then, the impact of the circuit nonidealities, such as noise and distortion, on the readout fidelity is investigated. Based on this study, the system-level specifications for readout electronics will be quantified. We will review the characteristics and behavior of CMOS active and passive components at cryogenic temperatures. While keeping the device characteristics and required specs in mind, the block diagram and circuit schematic, including low-noise amplifiers, mixers, and baseband amplifiers, will be designed and measured.

• M.Sc. In microelectronics.
• A strong background in analog, mixed-signal, and RF circuit design.
• Good presentation, writing and communication skills.
• Ability to work in an international, collaborative, environment.
• Demonstrable creativity and originality.
