straight to the problem. Here is a picture of frequency response of my amplifier in the simulator (LTspice or Pspice both give same results).
Normally, in the open loop i see a phase of 90° which normally tends to increase. In this simulation I see a phase that starts at 180°.
Generally, an amplifier that does not oscillate, when the band touches zero, the phase is not more than 180 °. So, is this amplifier an oscillator, or is it the other way around?
EDIT: This is the frequency response bypassing the input capacitor.
