OSCILLATION IN AMPLIFIERS Most amplifiers work without problems, but in some cases oscillations may occur with high frequencies/high gains and/or poor layout. The first step is to measure the frequency and amplitude of the oscillation. Use the internal triggering of…
Specifically How to Measure Noise when using AMI’s transimpedance and voltage amplifiers VERIFICATION When determining how to measure noise one question that is frequently asked is how to verify the noise performance of voltage and current amplifiers. This note suggests…
Introduction Design of Capacitor Charging Power Supplies: In order to power laser flashlamps, pulse forming networks, and other energy storage capacitor applications, the capacitor is charged up in voltage, then regulated. This creates an unusual and different situation from conventional…
Transimpedance Amplifier Selection Guide AMI designs and manufactures a range of Transimpedance Amplifiers for OEM, medical and research applications primarily for use with photodetectors. AMI’s amplifiers combine low noise, high gain, large dynamic range, and small package size. The key…
