摘要： A cryogenic integrated circuit or integrated module includes a travelling wave parametric amplifier or a Josephson parametric amplifier. The cryogenic integrated circuit or integrated module also includes an oscillator, a signal input, a biasing input, and a signal output. The oscillator is connected to an input of the amplifier and is configured to produce an oscillating drive signal. The signal input couples input signals into the amplifier. The biasing input couples biasing signals into the oscillator. The signal output conveys output signals from the amplifier out of the cryogenic integrated circuit or integrated module.

摘要： An RF receiver circuit configuration and design is limited by conditions and frequencies to simultaneously provide steady state low-noise signal amplification, frequency down-conversion, and image signal rejection. The RF receiver circuit may be implemented as one of a CMOS single chip device or as part of an integrated system of CMOS components.

摘要： A method for ramping a switched capacitor power amplifier is disclosed, where the switched capacitor power amplifier comprises a plurality of capacitors in a capacitor bank, and where a number of the capacitors in the capacitor bank are activated. The method comprises changing the number of capacitors in the capacitor bank that are activated, maintaining the changed number of activated capacitors in the capacitor bank for a period of time, and repeating the changing and maintaining, where a length of the period of time is varied between at least two repetitions of the maintaining.

摘要： A method and apparatus for achieving large susceptibilities and long interaction lengths in the generation of new wavelengths in the infrared spectral region. A process of resonantly enhanced four-wave mixing is employed, utilizing existing laser sources, such as the CO.sub.2 laser, to irradiate a gaseous media. The gaseous media, comprising NH.sub.3, CH.sub.3 F, D.sub.2, HCl, HF, CO, and H.sub.2 or some combination thereof, are of particular interest since they are capable of providing high repetition rate operation at high flux densities where crystal damage problems become a limitation.

摘要： A parametric amplifier having four substantially identical variable reactance diodes arranged in a bridge circuit supplied with a pump voltage and a signal voltage and developing an idler voltage when these voltage sources are each connected to the diagonally opposed terminals of the bridge and the idler current is contained within the bridge arms. The bridge arrangement provides inherent isolation of two and in some cases the three voltage frequencies. The aforementioned abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
