Practical circuit analysis of amplifiers is a broad detailed text for use at any level of analog electronic amplifier circuit analysis study the text begins with single stage transistor amplifiers and single stage jfet amplifiers with an emphasis of frequency response. Amplifier circuit the practical amplifier circuit below could be the basis for a moderate power audio amplifier it features a typical though substantially simplified design as found in modern amplifiers with a class ab push pull output stage and uses some overall negative feedback
