The paper proposes a set of experiments with CMOS transistor array, which is a part of EDUCHIP test circuit. The goal of the experiments is to examine the dependence of the performance of CMOS amplifiers from bias current and W/L ratio of amplifying transistors. For that purpose different topologies of CMOS amplifying stages are presented and circuits for testing their basic small signal parameters and characteristics are discussed. Generalized tabular and graphical results from practical measurements are shown. They can be used in research and education on microelectronic circuits.
