Chopper amplifiers are generally considered as a perfect choice in applications where DC precision is mandatory. This kind of amplifier uses a continuous time modulation technique to exhibit extremely ...
(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) All amplifiers have some current flow, termed bias current, through the input pins. In ...
How to effectively measure ultra-low bias current by recreating the measurement scheme from an app note. Measuring input capacitance and input current. Creating a better measurement environment. 3. Cp ...
An avalanche photodiode (APD) delivers a useful electron-multiplier gain and generally improves signal-to-noise ratio (SNR) in optical communication systems. An APD is similar to a PIN photodiode with ...
