Abstract - A general analytical model for the frequency-domain behaviour of current mirrors is presented. The proposed model accounts for high frequency effects. The validity of the model it is shown not to be technology dependent. In addition to this, a circuit-level model of the response is derived. The inclusion of this model into high-speed amplifiers macromodels proves useful when predicting phase margins.
