Multistage amplifiers are essential for driving capacitive loads that span from picofarads to nanofarads in applications such as sensor interfaces, high-speed data converters and power-management ...

In 2008, Bob Pease exchanged e-mails with Linear Technology’s Mark Thoren, me, and a few other friends. The subject was how an amplifier will oscillate if you put a capacitive load on it. Bob knew ...

There are numerous factors to consider when adding external capacitors to switched-mode power supplies (SMPS). This article will discuss noise, startup, ESR, stability, pre-bias applications, Sense ...

Driving capacitive loads at speed is difficult. The fundamental reason for this is that the current charging due to the voltage change is limited only by the equivalent series resistance (ESR), which ...

The DS-2100 and the DS-2100 WiFi displays from Loadstar Sensors Inc. are load indicators designed to work seamlessly with the company's patented capacitive load sensors. The DS-2100 and the DS-2100 ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Op amps are generally pretty easy to apply, but there are some practical nonideal behaviors you have to keep in mind. [EEforEveryone] takes a test board with some 2X amplifiers on it and — after some ...

Such cells also need a bulky and expensive signal conditioner to make them useful. Engineers at Loadstar Sensors, Mountain View, Calif. (loadstarsensors.com), use a capacitive sensing scheme in their ...

Op amps are generally pretty easy to apply, but there are some practical nonideal behaviors you have to keep in mind. [EEforEveryone] takes a test board with some 2X amplifiers on it and — after some ...

Increased electrification in vehicles is changing the way driver assistance systems are designed, says Yang Wang, with high-side switches increasingly used for resistive, capacitive and inductive ...

The use of air-break disconnect switches to interrupt the capacitive currents associated with open‑ended bus runs and short lines is common practice. In most cases, the current magnitude is no more ...
