  2. Class AB amplifiers have been the workhorses of the audio world, thanks to their simplicity, and their ability to deliver high power levels with low distortion. But there are also a number of gremlins that lurk within the AB architecture, mostly in ...

  3. The absolute-value amplifier is a basic building block in test-and-measurement and signal-processing applications. The addition of a DPP (digitally programmable potentiometer) adds another dimension, G (gain), to this key circuit. Because the gain ...

  1. The circuit in Figure 1 powers a microparticle and nanoparticle ion trap through a 1-to-5-turns-ratio, high-voltage transformer. It also works successfully as a driver for a piezo-tube scanner and in a near-field scanning optical microscope. The ...

  2. EDN A true-differential, power-source-free, high-input-impedance amplifier with bipolar output would present distinct advantages in remote devices. Such an amplifier, with its bipolar output, would be a better choice than a unipolar, 4- to 20-mA ...
