Photos: Artificial eyes and airport scanners - what's hot in R&D
Photo The device uses application-specific integrated circuits to transform digital images from a camera into electrical signals in the eye that the brain uses to create a visual image. The retinal implant receives a signal... [21 Aug 2009]
High-Linearity CMOS Feedforward Power Amplifier for WiMAX Application
White Paper In WiMAX front-end circuits, the power amplifier is an important component, which decides the transmission coverage and entire efficiency of the system. The Worldwide interoperability for Microwave... [23 Apr 2009]
Designing Bang-Bang PLLs for Clock and Data Recovery in Serial Data Transmission Systems
White Paper Clock recovery using Phase-Locked Loops (PLL) with binary (bang-bang) or ternary-quantized phase detectors has become increasingly common starting with the advent of fully monolithic Clock and Data Recovery (CDR)... [07 Oct 2008]
Feasibility of Flow-Based Optical Provisioning in GEANT
White Paper Historically, telephone calls were injected into circuits at the edge of the network, while data traffic was sent to an IP router towards a packet switched architecture. On the other hand, data... [11 Sep 2008]
Development of a Single-Chip RF Front-End LSI for Wireless LAN With Transmission Line Based Matching Circuits
White Paper In order to reduce the chip size, on-chip CPW lines has been employed to realize on-chip impedance matching circuits which saves 30-40% chip area than those using the spiral inductors. In Direct Conversion Receiver (DCR)... [06 Dec 2007]
Peter Cochrane's Blog: NGNs - real or imaginary?
Comment My first (personal) experience of a NGN came with the arrival of the transistor which immediately reduced equipment sizes and power consumption, and increased the number of speech circuits per pair. The next NGN involved... [02 May 2007]
HP Integrated Network Management System Makes Data Transmission Automatic - And Operators Happy
White Paper The company wanted to put an end to configuration nightmares by implementing a solution that automates the building of circuits for program data transmission. RAI Way also has more than 60 other access... [05 Jul 2006]
VoIP primer: How it works - and what the jargon means
Comment Even the migration from analogue to digital circuits did little to change this model. Transmission control protocol (TCP) arranges them in the right order. Ever wondered how IP telephony actually works? [10 Feb 2005]
Peter Cochrane's Uncommon Sense: VoIP spam - it's coming
Comment This is an impressive number that is not easily achieved without the duplication of switching and control circuits and power supplies. The transmission quality and call completion rate are monitored and... [08 Sep 2004]
