Primary analog circuit: overview of 5-1 power amplifier
Time：2020-12-7Back to the catalog All the amplifiers we analyzed in the previous chapters 3 and 4 are signal amplifiers, which are mainly used to amplify small voltage (or current) signals. Generally, we don’t need to consider the power limit too much. But there is another type of amplifier, its purpose is mainly to amplify power, […]

Primary analog circuit: 5-4 class B power amplifier
Time：2020-11-30Back to the catalog 1. Basic working principle Because the efficiency of class a amplifier is too low, it is usually only used for small power amplification or signal amplification. Class B (class B) or class A (class AB) power amplifier is really used for high power amplification. Class B power amplifier is characterized by […]

Primary analog circuit: 5-5 class A and B power amplifier
Time：2020-11-24Back to the catalog 1. Basic working principle The main structure of class A and B power amplifiers (class AB) is similar to class B power amplifiers, but it can eliminate the crossover distortion of class B power amplifiers. The corresponding cost is to increase a little static power consumption, so its efficiency is slightly […]
