Please help explain this voltage doubler circuit. I don't understand how point 2(the negative side of C1) can become positive all of a sudden and forward bias diode 1.
Someone tried to explain it like With V1 raising the + side of C1, node 2 will start to rise by the same amount, but is...
I've been reading about semiconductor physics of diodes.
For a PN junction diode, the total potential across the semiconductor equals the built-in potential minus the applied voltage.
Phi = Phi(built-in)-Va(voltage applied)
My question is what happens when the Va exceeds the Phi(built-in)...
I just have a few questions on the physical operations of the BJT.
1) Van Zeghbroeck's book says, The carrier densities vary linearly between the boundary values as expected when using the assumption that no significant recombination takes place in the quasi-neutral regions. Why would the...
What is the difference between RFIC and just plain RF/Microwave circuits? I know one is integrated circuit and one is just more traditional using surface mount(microstrip) etc. But my main question is in what applications do you need RFICs and when do you design just RF circuits.
Thanks.
