Lowering ispPAC frequencies to the audio range News & Analysis 1/24/2002 Post a comment The ispPAC family of analogue components gives the circuit designer the flexibility of designing general-purpose analogue signal processing applications using in-system-programming (ISP). Designs are completed on the PAC Designer software and downloaded to the devices in milliseconds allowing the completed design to be immediately evaluated. Configuration data is stored in non-volatile memory enabling retention of circuit designs while power is turned off.

Interface line topologies rule high-frequency applications News & Analysis 1/21/2002 Post a comment Engineers typically treat 3-inch-long traces as short interconnects, with few high-frequency considerations. But this approach often overlooks problems with interface operation or RF emissions, writes engineer Mike Grabois in this original contribution to Planet Analog. We need to recognize where various line topologies turn into transmission lines, he says.

Pro Logic II matrix decoder melds multimedia News & Analysis 1/9/2002 Post a comment As more people have come to appreciate the benefits of surround-sound playback, they also want nonsurround program material-particularly music-to take full advantage of their multichannel playback systems. This desire is not only for home theaters, but also for car audio systems, computers and even headphone listening. The Dolby Pro Logic II 5.1-channel matrix decoder was designed with these expanded uses in mind.
Digital pots shrink volume controls News & Analysis 1/9/2002 Post a comment In this circuit-oriented piece, Maxim's application guru gives pointers for giving digital potentiometers the logarithmic taper found in mechanical volume controls - and ensure left-right channels are balanced to within a few dB.
Decimation Stages with WDFs for Flexible Digital Receivers Design How-To 1/9/2002 Post a comment Dieter Brckmann of the University of Wuppertal, Germany, describes a decimation filter architecture for highly optimized but flexible digital receivers. By using cascaded low-order wave digital filters for certain blocks, you reduce hardware cost and get superior sensitivity properties with respect to coefficient quantization effects, better noise performance, and less group-delay distortion.
California Micro sees order growth, but still expects loss in quarter News & Analysis 1/7/2002 Post a comment MILPITAS, Calif.--California Micro Devices Corp. today affirmed previous estimates of $7-to-$7.5 million in revenues in its fiscal third quarter, ended Dec. 31, and a pro-forma net loss of $0.38-to-$0.40 per share, before restructure charges and other items related to the company's new manufacturing model.
