Power Factor Correction
Articles 11/26/2002 Post a comment
One of the leading topics in line-operated power-converter design is to take power from the grid but not give any back. In other words, wall plugs should present to the ac source a resistive (and not a reactive) load. A power-factor corrector is the interface between the ac line and power converter that achieves this. Innovatia Laboratories' Dennis Feucht explains what power-factor correction is and why it matters.
Efficient Testing of Analog/Mixed-Signal ICs using Verilog-A
Articles 11/13/2002 Post a comment
Verilog-A can expedite the painfully slow transistor level simulations of large mixed-signal ICs. Nitin Mohan of Sirific Wireless demonstrates that by converting the Verilog HDL models to corresponding Verilog-A models, the system level abstraction becomes possible at no extra cost of digital simulator.
A Simplified Algorithm for State Space Circuit Analysis

Robert R. Boyd provide a shortcut method to define the circuit state-space arrays, after which analysis can proceed directly to dc, ac, and transient responses with minimal effort. The method considerably reduces the amount of algebra required when compared to conventional state-space circuit analysis.
Input Filter Design for Switching Power Supplies
Articles 11/8/2002 2 comments
New technologies and components are prime movers in the design of higher efficiency and smaller switching power supplies. However, to optimize these power sources for cost and volume, you need to correctly design the supply's input filter. National Semiconductor's Michele Sclocchi explains how to choose and design the optimal input filter for a switching-power-supply application.
The Tuneable Pipelined Frequency TransformA New Filter-Bank Technique
Articles 11/4/2002 Post a comment
For certain applications, the Tuneable Pipelined Frequency Transform (TPFT) provides advantages over more conventional methods of frequency splitting, such as complex down-converters or the Discrete Fourier Transform. RF Engines' CEO and CTO, John Lillington, describes the TPFT architecture and reviews the advantages of this technique over competing solutions.
These days, I often code design equations for filter circuits directly into sequences of Excel cells
The introduction of the solar boat is necessary to preserve our planet, which is mainly covered by water; the autonomous drive option is a pleasant alternative
Leading up to APEC have been a slew of new introductions by various suppliers. I wanted to highlight some of that here on Planet Analog for your information
