In the paper an OTL power amplification circuit model is designed,based on Multisim10.0 which is an electronic simulation software. It is a power amplifier circuit prototype widely used in the present electronic products. The measurement and analysis of the circuit parameters including maximum undistorted power output and circuit efficiency, input resistance and output resistance, circuit upper and lower cut-off frequency are stressed. Practice has proved that the virtual platform can auxiliarily test the experimental circuit parameters. The purpose of low cost and high efficiency in the circuit experiment is realized.
