Re: AD734 Multiplier: Basic Circuit: ac simulation uses parameters from transient

a) Why is the .ac simulation influenced at all by the parameters of the
transient simulation?
In an .ac analysis, LTspice first needs to find the operating point. All
voltage and current sources are set to their values at t=0.

Since you specified a SINE source with a phase shift of 45 degrees, the t=0
value is 0.707* 3.0 = 2.12132V.
