Hi all,
How would I go about designing a voltage controlled phase shift?
I know that you could use an active amplifier (op amp configuration) and use a FET as a voltage controlled resistor with a capacitor to adjust the cut off frequency but thats very ugly. For one, different FETs have different characteristics so I dont want to be designing a circuit specific to a single FET.
Any ideas?
All the best,
Robin
