A novel type of multiloop DC SQUID (superconducting quantum interference device) has been fabricated. The device is made of six different layers deposited on a 2-in silicon wafer; the layers are patterned by means of optical lithography. Every chip is a square 6.35 mm on a side and contains two SQUIDs and their input coils; the typical coil inductance ...

An improved water faucet having a valve body with control elements formed by two discs wherein the first disc is stationary and has water inlet openings and an outlet opening, connected on one side to the valve manifold. The other side is directed toward the second disc, which is movably arranged on the first disc.

MHEMT G-band low-noise amplifiers
2013 IEEE MTT-S International Microwave Symposium Digest (MTT), 2013To improve the performance of G-band equipment for humidity sounding of the atmosphere, a high-gain and low-noise amplifier is needed. Here we describe and report the performance of several low-noise amplifier microchips intended for 183-GHz water vapor profiling application.

Compact Low-Noise Photonic Microwave Generation From Commercial Low-Noise Lasers
IEEE Photonics Technology Letters, 2017We demonstrate how phase-locking a whispering gallery mode-stabilized semiconductor laser to a high-stability Erbium-based distributed feedback fiber laser makes an outstanding optical reference for photonic microwave generation using an optical frequency comb. Using only commercially available compact lasers, it allows generation of a 12 GHz microwave

Low noise multiwasher superconducting interferometer
Applied Physics Letters, 1998The dc-superconducting quantum interference device (SQUID) is a low-noise converter from magnetic flux to voltage which can have, in principle, an energy sensitivity near the quantum limit of ℏ/2. A critical parameter for the ideal performance is the device inductance, which must be kept as small as possible.

A low noise 0.9 GHz FBAR clock
Analog Integrated Circuits and Signal Processing, 2005A low noise 0.9GHz FBAR clock consisting of an oscillator and divider circuit for single sided-to-differential conversion for high-speed A/D-converter was designed, realized with an in-house FBAR and a commercial 0.35 /spl mu/m CMOS process, and tested. The circuit showed very good jitter and phase noise performance.

A blower for fluidized particulates has a housing with an inlet in one wall. The housing defines a chamber which also has an outlet. A rotatably mounted shaft projects into the interior of the chamber. Circumferentially spaced around and projecting laterally from the shaft are a plurality of blades which individually have a shape selected to ...

Ostensibly, one key component of any receiver chain is the low-noise amplifier (LNA) coming off the antennas. Since the signal at that point is comparatively weak, good gain and noise performance are necessary.

Any analysis of single-channel current events needs sufficient resolution of the signals from the background noise, which is accomplished by reasonable low-pass filtering. An increase of the recording bandwidth is therefore possible only if the background noise in the recording system is reduced.
