... the required inductance value is high then only one source is connected to ground through this inductance. In the last two stages the inductance is low and therefore the two transistor sources are connected to ground, thus the inductance is half. Matching networks are mainly made up of capacitors an ...
So you think you have noise: high voltage amplifiers
... then by all means go for amplifier A. However, intrinsically, amplifier B is better: if its bandwidth were 100x smaller, like is the case for amplifier A, its output noise would be 200 µV. And if in addition its amplification factor were 10x instead of 50x just like amplifier A, it would provide 40 ...

100V - 100W DMOS audio amplifier with mute/st-by
... From fig. 20, where the maximum power is around 200 W, we get an average of 20 W, in this condition, for a class AB amplifier the average power dissipation is equal to 65 W. The typical junction-to-case thermal resistance of the TDA7294 is 1 oC/W (max= 1.5 oC/W). To avoid that, in worst case conditi ...

... • Electrical resistance can be thought of as the "friction" on the movement of electrons in a wire. Resistance is measured in ohms, and the unit symbol for it is the Greek letter omega, Ω. Thus 3 ohms is often written as 3 Ω. • Following the water hose analogy, resistance is similar to the friction ...
