Boost bridge audio amplifier
The main difference in topology of a boost bridgeamplifier and state-of-the-art class-D amplifier is in theconnection of a loudspeaker between a power supply and aswitching bridge. The boost bridge amplifier provides fourtimes higher peak power at the loudspeaker than the power,which can be achieved by a class-D amplifier from the samepower supply. Total harmonic distort...
متن کاملSupersonic Downflows in a Sunspot Light Bridge
We report the discovery of supersonic downflows in a sunspot light bridge using measurements taken with the spectropolarimeter on board the Hinode satellite. The downflows occur in small patches close to regions where the vector magnetic field changes orientation rapidly, and are associated with anomalous circular polarization profiles. An inversion of the observed Stokes spectra reveals veloci...
متن کاملImplementation of Latch Type Sense Amplifier
Sense amplifiers plays an important role in memories like Dynamic Random Access (DRAM) and Static Random Access (SRAM) for read and write operations. A sense amplifier compares the bit line voltage and its complement amplifies it to rail to rail output voltages. In this project, we mainly concentrated on the write operation. Sense amplifier is one of the peripheral circuits in memories that are...
متن کاملTunable ultraslow light in vertical-cavity surface-emitting laser amplifier.
We report the experimental demonstration of tunable ultraslow light using a 1.55 um vertical-cavity surface-emitting laser (VCSEL) at room temperature. By varying the bias current around lasing threshold, we achieve tunable delay of an intensity modulated signal input. Delays up to 100 ps are measured for a broadband signal with modulation frequency of 2.8 GHz. With a VCSEL design optimized for...
متن کاملPlasma Ejections from a Light Bridge in a Sunspot Umbra
We present conspicuous activities of plasma ejections along a light bridge of a stable and mature sunspot in NOAA 8971 on 2000 May 02. We found the ejections both in the Hα (10 K) images obtained with the Domeless Solar Telescope (DST) at Hida Observatory, and in the 171 Å (Fe ix/x, ∼106 K) images obtained with the Transition Region and Coronal Explorer (TRACE). Main characteristics of the ejec...
