Large signal Models take in to account the non-linearity of a device to some degree. If you change the Bias
on an Amp it will change its performance (more/less gain, different Optimal matching points). This is a Small
signal Model. Small Signal models are for devices that are used in there linear region (rule of thumb is 5-10dB
below the -1dB Compression point).
