Microstrip superconducting quantum interference device radio-frequency amplifier: Effects of negative feedback on input impedance
We present the results of measurements of the scattering parameters of microstrip amplifiers MSAs based on the dc superconducting quantum interference device. The amplifier input impedance is poorly matched to typical transmission line impedances, resulting in high input return loss around 2 dB. We show that negative feedback can lower the MSA input impedance to achieve a robust match to 50 . I...
متن کاملRadio Frequency-Single Electron Transistor: A Fast and Sensitive Electrometer Analogous to the Radio Frequency-Superconducting Quantum Interference Device
We describe a new mode of operation of the single electron transistor (SET). The so-called RF-SET (radio frequency-SET) is a dual of the RF-SQUID (radio frequency-superconducting quantum interference device). It has been operated at frequencies above 100 MHz with a very high charge sensitivity (1.2 3 10e/ÏHz). The large bandwidth, combined with a high sensitivity, will enable studies of the dyn...
متن کاملPinch resonances in a radio-frequency-driven superconducting-quantum-interference-device ring-resonator system.
In this paper we present experimental data on the frequency domain response of a superconducting-quantum-interference-device ring (a Josephson weak link enclosed by a thick superconducting ring) coupled to a radio frequency tank circuit resonator. We show that with the ring weakly hysteretic the resonance line shape of this coupled system can display opposed fold bifurcations that appear to tou...

متن کاملAluminum and boron nuclear quadrupole resonance with a direct current superconducting quantum interference device
We report the application of our dc SQUID (superconducting quantum interference device) spectrometer [C. Connor, J. Chang, and A. Pines, Rev. Sci. Instrum. 61, 1059( 1990)] to nuclear quadrupole resonance (NQR) studies of aluminum-27, and boron-II in crystalline and glassy solids. Our results give eqQ /h = 2.38 MHz and 1] = 0.0 for a-A120 3 at 4.2 K. For the natural mineral petalite (LiAISi4 01...
