EMI滤波器主要有无源EMI滤波器(Passive EMI Filter, PEF)和有源EMI滤波器(Active EMI Filter, AEF)[5-8]两种。PEF主要使用电感和电容来衰减EMI,而AEF主要使用晶体管和运算放大器(Operational Amplifier, OPAMP)将补偿电压或电流注入电路来衰减EMI[9]。
Here is an audio amplifier using PUSH PULL mode to drive a speaker: The top two transistors are in push-pull mode to turn the P-channel MOSFET on and off very quickly. They speed up the incoming waveform and prevent the MOSFET generating heat during the turning-on process. ...
Linear/Ohmic Region –It is the region where the current across the drain to source terminal enhances with the increment in the voltage across the drain to source path. When the MOSFET devices function in this linear region, they perform amplifier functionality. ...
