Hi,
A CE amplifier (or equivalent) with a gain of 1 should be a 180 degrees phase shifter and a CC amplifier (or equivalent), if there is need at all, will give you a 0 degree phase shift.
I believe you are left with the 90 degrees and 270 degrees phase-shifters.
...
But i am looking for a complete circuit which will output all the phases.
This circuit looks good and straightforward. Is there any simulator where i can change the value of these R and C according to my voltage(almost >50V amplitude) and frequency(50khz).Sine sources 5V amplitude each. Total 10V.
Component values need to be adjusted for your source voltage and frequency.

Also one thing more to mention here is that i do not have 2 signal sources available as shown in the solution
Something like this you mean(sorry for bad drawing):I think my solution would be to drive two transformers, each having a center tapped secondary. The taps would be the output 'ground' and the winding ends would give outputs inverted with respect to each other (0, 180). Then by adding an LC delay between the primaries, the second transformer phase could be shifted 90 degrees giving the 90, 270 shifts. The only drawback would be the slight shift introduced by the transformers themselves but the OP doesn't specify whether the outputs must be exactly in phase with the inputs. Any circuit would introduce some shift anyway.

Not quite, but nearly!Something like this you mean(sorry for bad drawing):
The transfer function of this circuit can be easily calculated and also found in many literature sources, e.g. here https://en.m.wikipedia.org/wiki/All-pass_filterIn the all pass filter design Post#7, how would one translate the effect of potentiometer in terms of phase shift.
NopeWill this work at 500khz?
