A widely-used push-pull configuration of an AB class amplifier is shown in Figure 1, but it needs some improvements. Figure 1. This configuration of an AB class amplifier have some improvements. First of all, let’s take a look how its thermal ...
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 ...
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 ...
