How a phase shifter can be implemented using BJT?

[kidia]

I need a help on this,can anybody explain or give me a site showing how a phase shifter can be implemented using BJT?

Re: Phase shifter

any class a a-b or c device circuit using any transistor will shift phase by 180 deg anyway


90 deg takes capacitance,,,

Phase shifter

Also a transformer gives 180 deg phase shift

Phase shifter

CE transistor is a 180 degree phase shifter...
also circuit built by passive elements can offer phase shift from 0 to 90 degree which depends on elements value.....

NOTE : i dont think that it is possible to built a perfect phase shifter

Re: Phase shifter

You can use an all pass op-amp based filter. Please check out next link for an audio continuous phase shifter: h**p://sound.westhost.com/project103.htm
