Thus far we have been focused on large signal modeling with Verilog-A in the time domain. A large signal is any signal having enough magnitude to reveal a branch's nonlinear behavior. A small signal analysis assumes that variations in signal potential and flow amplitudes are so small that the branch constitutive relationship can be assumed to behave linearly. Practically, the small signal analysis models are obtained by linearization of the nonlinear branch constitutive relationships near a static operation point. It allows performing the small ...
