Starting with a simple basic amplifier, we consider multri-stage amplifiers with feedback, the differential amplifier, low noise amplifier, microphone pre-amplifiers, operational amplifier and power amplifiers of class A,B,C and D. Practical design procedures are described.Raczynski, Stanislaw...
Many car audio amplifiers have what is called an unregulated power supply. The power supply is what converts the vehicle's charging voltage into power that the amplifier can use. And if the power supply is an unregulated design a boost in voltage from the vehicle means a boost in power fro...
Reducing voltage supply is one of the most effective way to reduce the power consumption, but, on the other hand it is a challenging choice for the analog designers. In this paper, different topologies, well-suited for low voltage and ultra-low voltage supply, are depicted, investigated, desi...

如果预算不是问题直接买足配件(Tuner & High Power Amplifier)是最省事的,这里主要是用Antenna Tuner Vpeak这主题来介绍阻抗转换与电压增益的关系,这个原理与Antenna Tuner为什么会承受大电压是相同,也复习一下传输线阻抗匹配的有趣性质,从中可以理解为什么Antenna Tuner需要设计承受这么高的电压Vpeak,如果有其他问题要讨...
A voltage-power booster for an operational amplifier employs positive and negative voltage amplifier circuits connected to the positive and negative voltage supply terminals of the operational amplifier to produce output voltages for positive and negative signals which exceed the rated output voltage of th...

The amplifier output provides variable drive current directly to a base of the first transistor, thereby enabling increased drive current to be realized. The power amplifier also includes a common mode biasing circuit connected to bias the first and second transistors for class AB operation, and ...
