Most often capacitor selection to the uniformed seems like a simple choice but the demands, challenges and expectations of modern electronics prove otherwise. As more electronic systems continue to be integrated into our automobiles, the need for capacitor technologies that deliver high reliability, long life, stable performance,...

Trimming potentiometers or “trimmers” are mechanically adjustable resistors utilized in electronic circuits to balance out component tolerances, and to adjust the behavior of the circuit. Bourns now offers a trimmer that can be adjusted to a more precise linear output and lower Contact Resistance Variation...

This introduction to EPAD MOSFET describes a broad selection of devices with precisely set gate threshold voltage values, including zero threshold made, enhancement mode and depletion mode. Furthermore, novel circuit designs are presented to illustrate how these devices can be used at a practical level. The brief circuit...

Connectors are often seen as the weakest link between sub-systems, and sometimes this is rightly so. This can be as a result of underspecifying the connector system or not appreciating the difference between the various rating schemes. As a result engineers tend to over-specify the connectors to ensure they are reliable...

Beside the common advantages of a flyback converter, it has inherently parasitic components, which typically produce ringing waveforms with considerably high voltage spikes. This ringing can also influence the EMI emissions adversely. Therefore, it is an important task to adequate suppress and damp the ringing effect....

Power has always been a design consideration. Traditionally, though, a lower priority has been assigned to power than to most other variables (speed/performance, cost, time-to-market, risk, etc.). In today’s marketplace, however, power has become a very important component in the designer’s decision making...

This paper shows the need for a new impulse response model and proposes a methodology for its inclusion in timedomain simulations.
The paper also solves another difficult problem by presenting a new technique for converting band-limited S-parameters into ‘base-delay’ causal and passive impulse response...

The most common gate oscillator in use today is by far the Pierce-Gate. Its popularity stems from the fact that the digital inverter, U1, is usually included in the microprocessor or ASIC the designer selects. In effect, the oscillator cell U1 is free!
This whitepaper will analyze how the Pierce-Gate oscillator functions...

This article examines how to synchronize multiple DC/DC buck regulators in a Master/Slave configuration using phase shift time delay. Phase shifting multiple converters prevents ON time overlapping and reduces RMS current, ripple and input capacitor requirements, which will improve system EMI and power efficiency. This...

Ethernet seems to be one of the fastest growing transmission protocols ever, on both medium types, fiber and copper. Over fiber it easily reaches 40G and 100G transmission speed but in the future it may achieve even 400G or tera-level speed.
Over copper, of course, much lower speeds are achieved and 1G Ethernet has...

Power consumption is becoming an increasingly important variable when it comes to calculating OPEX and carbon footprint for telecom infrastructure projects. For example, on average, each fully loaded 3G cell site costs approximately $1600/yr US or $3200/yr in Europe. In addition to these costs, the level of consumption...
