Abstract
Bipolar emitter-coupled pairs are basic building blocks in many analogue integrated circuits. Because of the high intermodulation and adjacent channel radiation performance requirements, state of the art communication electronic circuits require extremely linear transfer functions of the emitter-coupled pairs and several techniques have been proposed for their linearization. In this paper, a comparative study of these linearization techniques is presented. A simple procedure for approximating the transfer characteristics of an emitter-coupled pair is proposed and closed-form expressions are obtained for the amplitudes of the intermodulation products at the output of an emitter-coupled pair excited by a multisinusoidal input signal. Using these expressions comparison between the different linearization techniques can be performed and the optimum linearization technique required to meet a predetermined intermodulation performance can be decided.
