Abstract This article details a method of generating dual-output voltage rails that provide both the positive and negative rails for a device power supply (DPS) while requiring only one bidirectional power supply. The traditional method of powering ...

Abstract This article will explain the inherent limitations of the boost topology and how to overcome them. When designing and evaluating boost converters, sometimes the intended output voltage is not realized. Instead, it has a lower value than ...

Figure 1 shows the architecture of a conventional isolated flyback converter. These converters can be found frequently in power classes of up to about 60 W. A supply voltage is converted to an output voltage with the help of a primary-side switch ...

Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts. Also, unless the converter is driven differentially, the noise ...

Many precision test-and-measurement and high-speed analog applications require an exact targeted voltage to be delivered to the device under test or intended load to accurately analyze the device. Design and test engineers are well-aware that this ...

Despite massive, large-scale integration being ubiquitous in contemporary electronic design, discrete MOSFETs in the classic CMOS totem pole topology are still sometimes indispensable. This makes tips and tricks for driving them efficiently with ...

Abstract This article discusses the use of dynamic voltage scaling (DVS) to achieve precise voltage regulation. DVS is a process that adjusts the output voltage slightly higher or lower in anticipation of load transients. The article examines how ...

FinFETs redefined chip design when they came onto the scene more than a decade ago. While these nonplanar transistors are still the unofficial industry standard, they may be nearing the end of their life. So, electronics engineers may need to ...

A recent trend in the design of portable devices has been to use ceramic capacitors to filter DC/DC converter inputs. Ceramic capacitors are often chosen because of their small size, low equivalent series resistance (ESR) and high RMS current ...

Introduction Electronic equipment uses predominantly positive voltage rails for power. Occasionally, some negative voltage rails are also used. For this reason, negative (or inverting) output DC/DC converter solutions are not as common as their ...
