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 ...
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 ...
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 ...
