    PHASE SHIFT IN AN AMPLIFIER

    To Irstuff. You are right –it’s the relative phase between Vref and outputs what counts. And so was my initial question: how to shift sinusoidal signal with minimum hardware? It has to be moved to ~10° “left” (if you look on scope) or ~350° to the “right”. Latter is less realistic-it’s almost...

    PHASE SHIFT IN AN AMPLIFIER

    To Irstuff. As an Aerospace dude :) your probably familiar with Arinc565. My outputs are an altitude syncros and the Vref is an aircraft 400 Hz power line which NOBODY let me delay. And that new Ref should rather precede the outputs isn’t it? Thank you.

    PHASE SHIFT IN AN AMPLIFIER

    It's about 36 mikrosec. Thank you.

    PHASE SHIFT IN AN AMPLIFIER

    Hi. My circuit is suppose to produce 4 output sinusoidal signals with different (and switchable) amplitudes. It should be out of phase with Vref = 400 Hz sinus which I use as Vin for the first stage differential amp. The signal is then split into four branches with different gains. The three...

    PHASE SHIFT IN AN AMPLIFIER

    Hi. I am a new member. My question is: I have an unwanted phase shift (~10œ)from the input sinusoidal signal in a three stage amp. Is there any simple way to shift it back (or forward to~170œ)? Will a negative feedback with a cap in the middle do? Thank you.
