1) What is the Barkhausen criterion, i.e. what is the loop gain magnitude and a. phase criteria for achieving oscillations? Assume positive feedback such as in the Wien- Bridge oscillator. b. What conditions must be true about an ideal op-amp circuit in order for us to assume the voltage between the inverting and non-inverting terminals is zero volts?
