Reset Noise at Low Temperatures

This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...

Thermal Time Constant Measurements for Ge Film, GaAs Thermometers at Low Temperatures

In this experiment, thermal time constant measurements were taken from a system consisting of a heater, He gas, and a sensitive, low temperature resistance thermometer. The resistance thermometer [3] was made of a Ge film deposited on a GaAs substrate. The data from this experiment will be used to design a mass measurement system for hydrogen storage tanks in micro-gravity environments. INTRODU...

A Concurrent Dual-Band Low Noise Amplifier for GNSS Receivers

In this paper, a new design of concurrent dual-band Low Noise Amplifier (LNA) for multi-band single-channel Global Navigation Satellite System (GNSS) receivers is proposed. This new structure is able to operate concurrently at frequency of 1.2 and 1.57 GHz. Parallel and series resonance parts are employed in the input matching in order to achieve concurrent performance. With respect to used pse...
