Hello guys,
I have simulated two circuits, one is an RC filter and other is a Capacitance multiplier.
My aim of experiment is to validate a decrease in Iout (load current) of CM circuit as compared to load current in RC filter circuit.
Theoretically,
Iout (CM circuit) < Iout (RC filter)
Vp-p...
Thanks for your reply.
Ok I got it what you are trying to point out.
With the presence of Zener the base voltage is held constant against any variation of source and load voltages and current, thus the output voltage is only the function of Vbe, as if Vout changes due to load variation...
Thanks for your reply,
I am looking it another way, first I am seeking to gain an intuition about how this circuit works, then I would be doing some circuit analysis to find out the values of circuit parameters and finally the last and the most important, i.e to run this circuit simulation to...
Hi friends,
According to text…due to zener diode, Q1 is supplied with constant base voltage.
Any change in output voltage is sensed at at the emitter of Q1 which brings change in forward bias of the transistor. Thus transistor changes its resistance at CE junction and compensates for the...
Hello Friends,
I have recently came across a text of impedance transformation provided by a tapped capacitor arrangement.
Its a rare and unique text explaining the working of tapped capacitor network in terms of conservation of power.
figure 6.31a) is an untapped case when no tapped capacitor...
Hi,
The following is a part of IF section of a television receiver...
As it is being visible that the output response of the IF section in superheterodyne receiver has a sharp slope which is necessary for correction of output response of video detector. It has been said that this sharp slope...
I know about the calculations as I watched the video..but what I want to ask is why or how do the imaginary parts of impedance of inductor as well as capacitor cancels each other..... ??
Hi friends,
I went through this extremely helpful and informative thread.... post 3.... and knew about the physical significance of imaginary part of the impedance.
Here I am presenting a circuit which is an L network used for matching.On simplifying the circuit the equivalent circuit is shown...
pls explain me the working of this circuit.The text says that Current source Q1 functions as usual but with collector volt- age held fixed by Q2's emitter...i.e the collector voltage of Q1 is held fixed by action of transistor Q2.But what i didnt digest is that if the temparature changes then...
