Sometimes, the need arises for a low-distortion buffer amplifier capable of handling bipolar signals. You can use an op amp or integrated buffer for these applications, but for more flexibility, a discrete design may prove useful. Applications ...
The circuit in Figure 1 is suited for inductive sources such as a dynamic microphone, transformer or inductance sensor/pick up. Figure 1. A simple amplifier circuit suited for inductive sources such as a dynamic microphone, transformer or ...
Engineers often perceive RF-low-noise-amplifier design as a difficult task. Obtaining a low-noise figure with high stable gain can be challenging even intimidating. However, with the recent evolution of GaAs (gallium-arsenide) heterojunction FETs, ...
