Bridge Tied Load Amplifier

Bridge Tied Load Amplifier: All of the power amplifiers already discussed have been single-ended (SE): meaning that they provide power to a load that has one terminal grounded and the other terminal connected to the amplifier output. These amplifiers either use a plus-minus supply with directly-coupled loads, or have a capacitor-coupled load and a single-polarity […]

Audio Power Amplifier using IC Amplifier Driver

Audio Power Amplifier using IC Amplifier Driver: The LM391 integrated circuit Audio Power Amplifier using IC Amplifier Driver contains amplification and driver stages for controlling an externally-connected Class-AB output stage delivering 10 W to 100 W. The voltage gain and bandwidth are set by additional components. Internal circuitry is included for overload and thermal protection, […]

Complementary MOSFET Common Source Power Amplifier

Complementary MOSFET Common Source Power Amplifier: Advantages of MOSFETs: Complementary MOSFET Common Source Power Amplifier have several advantages over power BJTs for large signal amplifier applications. One of the most important differences is that MOSFET transfer characteristics (ID/VGS) are more linear than IC/VBE characteristics for BJTs. This helps to minimize distortion in the output waveform.
