There are actually two inputs here, an inverting (-) input and a noninverting (+) input, just like in an op amp. the noninverting input is usually used for the signal input, and the inverting input deals with feedback. In all audio amplifiers, the feedback exists in …

produce high power to drive some output device. Audio amplifier output power may be a nything from less than 1 Watt to several hundred Watts. Radio frequency amplifiers used in transmitters can be required to produce thousands of kilowatts of output power, and DC amplifiers used in electronic control systems may also need high power outputs to drive motors or actuators of …

The audio power amplifier is used to amplify low-power audio signals to a level that can be suitable for driving the loudspeakers. Thus the audio power amplifier becomes a kind of essential part in the electronics that could make sounds. In this thesis, a good performance audio power amplifier with tonality control is designed. It

speakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source

Class A power amplifier. Class A power amplifier is a type of power amplifier where the output transistor is ON full time and the output current flows for the entire cycle of the input wave form. Class A power amplifier is the simplest of all power amplifier configurations. They have high fidelity and are totally immune to crossover distortion.

• Class A amplifiers are the least efficient of all amplifiers • Since most active devices have different clipping characteristics in cut off or saturation, class A amps often exhibit asymmetrical clipping. • Class A amplifiers are the most common in older smaller amplifiers because of the low part count.

Question 1 Fundamentally, an amplifier is a device that takes in a low-power signal and outputs a magnified (power-boosted) facsimile of the input signal. Explain how it is possible for such a device to exist. Doesn’t the Law of Energy Conservation (“Energy can neither be created nor destroyed”) preclude the existence of a power-boosting device?
