Hi every one.
i am working on small project. I've designed an oscillator using op-amp. the problem is the op-amp can supply 20mA of current but i have to take current to 4A. so i have to use a current Amplifier. i have decided to use a series of common collector amplifiers as the current Amplifier. but the Problem is that i am getting 8v RMS with 20mAout form my oscillator. 20mA is OK but i can't just apply 8v across base-emitter junction of a transistor. i was thinking to use 2N3904 transistor as the amplifier but look at the data sheet. The data sheet tells us that it can only handle 6v at the base-emitter junction. so tell me how to find a transistor according to my requirement?
i am attaching the data sheet (TO-92 case)
