How to avoid amplifier output driver saturation when using very low bias current amplifiers with high source impedance sensors, write Jon Munson and Kevin Scott When taking sensor measurements, the ...

(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 ...

Class B amplifiers are prone to crossover distortion, which occurs in the output stage in which conduction transfers from one transistor to the other. To prevent crossover distortion, a bias current ...

If you've ever designed an RF oscillator, you've probably encountered squegging. Sometimes called "motor boating," squegging causes oscillators to start and stop at frequencies much lower than the ...

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 ...
