Phase Shifter

  1. Apr 28, 2006 #1
    Can anybody explain to me what and how a phase shifter can be implemented using BJT.or give me the site which can get more details about this.

    Well, in the analogue treatment, look up Bessel filters: they implement linear phase shift. As Bessel filters are pure-pole filters, they can easily be implemented with a few amplification stages (using your BJT if you like) and passive R and C components...

    See for instance: http://www.filter-solutions.com/bessel.html

    (there are probably better sites around for that, but it is a start).

    Now, maybe you do not want to have a linear phase shift, but something else. Then you'll have to be more specific...
