When waveform read-outs come from a SPICE simulator
In a simpler time there wasn’t a great need for electronic simulation because equipment composed of discrete components could easily be bread boarded and powered up to try out ideas. This approach is now unfeasible thanks to billion-component ICs, multi-gigahertz bandwidth requirements, parasitic impedances, and electromagnetic interference issues. Rather than manually building and testing multiple […]

Basics of modeling transistors
By David Herres All transistors operate according to the exact same physical principles as diodes, the only difference being that they have greater complexity because there are additional P-N and N-P junctions and accordingly more terminals. As with simple diodes, a transistor junction conducts when it is forward biased and does not conduct when it is reverse […]
Understanding the Basics: What is Characteristic Impedance?
By David Herres We speak of 50- or 75-Ω coaxial cable. The novice wonders if these numbers apply to a given length, say 100 ft. Could you connect an ohmmeter to one end of the cable and expect to get that reading with or without the conductors shunted at the far end? The answer is absolutely not. […]
Floating Switch from TI Transforms Offline LED Drive Design
Texas Instruments (TI) (NASDAQ: TXN) introduced the industry’s first floating switch architecture that simplifies the offline linear drive of LEDs in lamps, downlights and fixtures. The AC switched matrix technique features TI’s TPS92411 floating MOSFET switch and is an innovative approach to producing low-ripple LED drive current without magnetic components. The architecture provides excellent compatibility […]
