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 […]

Contoured, modular ergonomic grip
The Contour Grip is a modular ergonomic grip that incorporates controls on the front, side and back. Its ergonomic design was created with feedback from experts in the field including machine operators who tested it in a virtual reality environment. The shape was refined after multiple modifications to come up with the final user-friendly version. […]
Dynamic testing saves energy, time and money
Dynamic testing of performance factors for a Department of Defense (DoD) customer’s helicopter transmissions, primarily in the Apache and Blackhawk classes presented a challenge, which involved an existing bank of over 20 individual test stands. The existing test stands ranged from 20–50 years in age and had been built with single-purpose functionality. The stands suffered […]
Fast 16-bit digital-to-analog converter at 1.5 GSPS
Texas Instruments Incorporated (TI) (NASDAQ: TXN) introduced a new 16-bit digital-to-analog converter (DAC). The quad DAC34SH84 is 50-percent faster and uses 50-percent less power than the closest 16-bit DAC alternative, clocking in at 1.5 GSPS and consuming just 362 mW per channel. The DAC34SH84 provides an easy, pin-compatible upgrade from the 1.25-GSPS DAC34H84 for customers wanting […]

PCB Design, Bringing It All Together
For anyone who has ever turned a PCB it is an obvious thing to ask for but we have all just stopped asking because one might die before it ever occurred: Integration between part manufacturer, distributor, PCB house, and PCB design tools into a development environment for the engineer. The esoteric electronic design automation (EDA) tools for the printed circuit boards of today could use some help. And that is putting it nicely.
