    simulate 741 op amp is spice

    Hi yes I want to simiulate the internal circuit of 741 op amp. but I don't know which specifications for transistors shoulde be used? I use some kinde of transistor which is in pspice simulator, but the bias point of op amp doesn't work properly.for example current mirrror dosen't mirror current...

    Help me with tail pulse current shaping

    hello.I want to LC Oscillator with a pulse current in tail. or cross-coupled transistors work in class C so that peak of current be in the peak od the output voltage. can any one help me?
