There are 4 SCR and 2 diode.
After drawing the output voltage I would be grateful if someone could calculate the Mean voltage.
In your case out put voltage ( average ) can be easily calculated by the formula : sqrt(1/T integral over Vm^2 sin wm^2 dt ) from zero up to the firing angel .
But of course i hope you know

I am new to photodiodes and their usage, please some one will solve my problem,
I am using the PIN photodiode and avalanche photodiode in photovoltaic(zero bias) modes. But i am unable to get the pulse of 50ns (sending from the laser).
I am sending the 50ns pulse from laser and the APD is placed at

I want design a Return to zero optical link with variable duty cycle.
I started it from 50% duty cycle.
Following is my block diagram. Basically, I use a and gate to generate 50% duty cycle Return to zero(RZ) signal
and use D flip flop to recover the signal to Non-Return-zero.

hey u means ∂^2 π=0 na?
then well i dont know the exect derivation but del= partial derivatives...
and the pie is a if u go for double derivatives of pie it will be zero only..
that was as per the best of my knowledge...

Magnetic field outside a long solenoid can never be zero. Because a solenoid of finite length will have edges and field will come out. However, if we imagine a straigth solenoid of infonite length or a toroid, it will not have edges from where lines of force can come out. therefore field would be zero outside a toroid or a strigth solenoid of infil

I don't have installed PCAD for testing but it might work by copying the refdes from silk screen to another unused layer. This is a common way for CADs which don't allow multiple RefDes. It works in Eagle.
What is zero point ?

If you are talking about power line zero crossing, then have a look at microchip application note AN958, you will find the answer there.

The descprepancy might originate from your hand calculation is not accurate enough: the Cgd of the input transistor is not easily calculated by hand. You should rely on the simulator to give you more precise number.
A sanity check also reveals that the zero can not be at over 100GHz frequency. 40~50 GHz is a more reasonable number.
