“…For example, when designing a circuit for a low-temperature amplifier, such as the one used for space technology and satellite communications, one needs to perform a test at room temperature (RT) first. When cooling down the amplifier, its characteristics can be significantly different since the resistance of the device based on HEMT structure may be a lot lower than that at RT [ 24 ]. Therefore substantial variation in the circuitry design based on the RT test is required.…”

A delta-doped quantum well with additional modulation doping may have potential applications. Utilizing such a hybrid system, it is possible to experimentally realize an extremely high two-dimensional electron gas (2DEG) density without suffering inter-electronic-subband scattering. In this article, the authors report on transport measurements on a delta-doped quantum well system with extra modulation doping. We have observed a 0-10 direct insulator-quantum Hall (I-QH) transition where the numbers 0 and 10 correspond to the insulator and Landau level filling factor ν = 10 QH state, respectively. In situ titled-magnetic field measurements reveal that the observed direct I-QH transition depends on the magnetic component perpendicular to the quantum well, and the electron system within this structure is 2D in nature. Furthermore, transport measurements on the 2DEG of this study show that carrier density, resistance and mobility are approximately temperature (T)-independent over a wide range of T. Such results could be an advantage for applications in T-insensitive devices.

“…This new level can be either above or below the original voltage level, depending on the present state of the system and the type of pulse used. Provided it is possible to reduce the ambient voltage noise on the SQUID ring sufficiently, for example by the use of cryogenically cooled GaAsFET [1] or HEMT-based preamplifier electronics [23], it should prove possible to develop devices with a controlled voltage response which can be selected, and modified, at will. This could prove useful in such areas as multi-level logic or finite state machinery [18,19,20,21,22].…”

In this paper we study numerical solutions to the quasiclassical equations of motion for a superconductingquantum-interference device ring-radio frequency ͑rf͒ resonator system in the regime where the ring is highly hysteretic. In line with experiment, we show that for a suitable choice of ring circuit parameters the solutions to these equations of motion comprise sets of levels in the rf voltage-current dynamics of the coupled system. We further demonstrate that transitions, both up and down, between these levels can be controlled by voltage pulses applied to the system, thus opening up the possibility of high order ͑e.g., 10 state͒, multilevel logic and memory.

An optimized TO-38 package design for the enhanced 3-dB bandwidth has been presented. The S parameters of the TO-38 package was measured and compared to the 3D simulation. A good agreement between the experiment and simulation was obtained. New optimized physical geometries for the TO-can package-bondingwires, leads, and material-show that this package can be used up to 15 GHz. This optimization technique will allow the TO-can package to be applied in an optical transceiver module up to 10-Gb/s.
