This paper describes a high voltage line interface circuit for low cost PBX applications which includes (1) Fibe 300V switches for opening the channel, ringing access and message waiting; (2) Ringi
A description of the internal block diagram is presented along with some of the feedback loop stabilization considerations.
A digital light deflector ( D L D ) is a device t h a t can switch a light beam to a number of distinguishable positions and has been previously described by a number of authors.
We propose an improved sectorization scheme, called narrow-beam quad-sector cell (NBQC) for cellular networks, in which each cell is divided into four sectors and each sector is covered by a 60/spl
In this paper, a novel high-efficiency four-stage Doherty power amplifier architecture convenient for practical implementation in base station applications for modern communication standards has be
:A highly efficient configurable three-wavelength cascaded Raman laser suitable for broadband Raman amplification is demonstrated.
This paper presents a high-fidelity speech and audio codec operating at a sampling rate of 32 kHz and a bit rate of 64 kbit/s.
Recent work x - 2 concerning diffusion of impurities into germanium and silicon prompted the suggestion 3 t h a t the dimensional control inherent in these processes be utilized to make high-freque
A high-performance and compact 40 Gb/s driver amplifier was realized in a 1.2 um emitter double-heterojunction InGaAs/InP HBT (D-HBT) technology.
One way to reduce the lengthy CPU time in fault simulation of a VLSI circuit is to model its functional primitives using high-level description languages such as C.
