Paper Abstract

A device that permits combining high impedance semiconducting IR detectors with low impedance superconducting electronics will have significant benefits for IR sensor systems. We report an improved hybrid three-terminal transimpedance amplifier with significant current gain. The TIA consists of a semiconductor diode configured for injection of electrons into a thin base electrode (less than 25 nm) superconductor-insulator-superconductor junction, whose response is read out by low impedance superconductive electronics. We achieved an input dynamic impedance greater than 10 exp 11 Ohms, an output dynamic impedance of approximately 10 micro-Ohms, a current gain of 20 and an effective input noise current less than 10 exp -14 A/sq rt Hz. We operated the TIA in a sensor test bed with an extrinsic silicon IR detector and a superconductive analog-to-digital converter.
