    Discrete Voltage Regulator w/ BJTs

    I did look at the paper you referred me to, but still there is one little problem that I'm having. All these designs use an error-correcting op-amp. I understand it's simply a negative feedback comparator kinda thing, no? or is there something else to it? in any case, I can't use an IC, so how...

    Discrete Voltage Regulator w/ BJTs

    Yeah i did make a circuit in which i used CE configuration for two NPN transistors, one after the other, where the voltage at the base of Q1 was set by a rheostat and the base of Q2 was attached to the emitter of Q1. Pathetic line regulation, as you pointed out, yet it may be because i have no...

    Discrete Voltage Regulator w/ BJTs

    Hi, My problem is very simple, I have a project in which I have to design a voltage regulator out of discrete BJTs, Zeners and resistors etc. the only limitation is that I cannot use an IC. I would prefer not using a zener because i would like to make the output variable through a voltage...
