In a charge-coupled device, as described by Boyle and Smith, 1 charge moves successively from the semiconductor region under a given electrode to the region under the next electrode.

The Double Heterostructure Opto-Electronic Switch is demonstrated as an N-channel, single quantum well, graded index laser structure.

A doubly periodic dispersion map scheme is proposed for 10- and 40-Gb/s hybrid dense wavelength-division-multiplexing optical mesh networks, which brings residual dispersion between optical add-dro

A circuit modeling drain-lag effects has been added in a non-linear electrothermal model for AlGaN/GaN HEMTs.

Smectic C has a layered structure on a microscopic length scale and is a two dimensional anisotropic liquid in the plane of each layer.

Texas Instruments has announced three new versions of its C62xx DSP architecture, the C6201B, C6202 and the C6211.

A Mobile fronthaul link that can facilitate 96 channels of 20MHz 64QAM LTE formatted signals over 20km fibre has been demonstrated, due to adaptive channelization and pre-compensation for downlink

The implementation of advanced DS-CDMA receivers based on multiuser detection principles is becoming a reality thanks to the combination of an improved understanding of the theoretical basis of mul

A dual channel SIGMA DELTA voicband codec meeting AT&T/CCITT specifications is described. The active area per channel is 13 sq. mm in a 1.5mu CMOS process.

The use of oversampling and decimation for analog-to-digital converters has the advantage of requiring no precision analog components, and since most of the circuitry is digital, it benefits from t
