Efficient Algorithms for MPEG-4 Video Decoding Design How-To 12/17/2002 Post a comment Efficient, programmable video decoding is critical for emerging mobile devices. J. Geoffrey Chase and Christopher Pretty from the University of Canterbury, New Zealand describe efficient algorithms for MPEG-4 video decoding and quantify the impact of accelerating co-processors for creating fully programmable MPEG-4 decoding solutions.
Estimating MOSFET switching losses means higher performance buck converters News & Analysis 12/11/2002 3 comments Lower voltages, higher current, and faster load slew rate pose a constant challenge for power supply designers. New-generation MOSFETs, high performance capacitors and new multiphase structures pose new challenges, writes this well-versed engineer.* Distributed power architectures - like Point of Load (POL) designs - will benefit from an understanding of MOSFET switching losses, he points out.
Tandem RF software programs streamline the design of power amplifiers News & Analysis 12/10/2002 Post a comment Harmonic-balance simulators - used in tandem with synthesis software that builds impedance matching networks -- can speed the design of RF power amplifiers. Engineers at Aerial Facilities in the UK show the steps they took to build a tunable 23-dB LDMOS amplifier with a center frequency in the 400-MHz range.
