Abstract New circuit models of ‘Complementary-Symmetry Class-AB and Class-B Push-Pull Amplifiers’ are proposed. The proposed Class-AB amplifier circuit, configured by matched Darlington pairs, possesses 62.83% efficiency with low harmonic distortion (0.94%). However the proposed Class-B amplifier that is configured by using Triple Darlington configuration of matched BJTs, produces improved efficiency (73.28%) on the cost of enhanced harmonic distortion (1.23%). The proposed circuit model of Class-B Amplifier is perhaps a fresh approach. Variation of efficiency and total harmonic distortion as a function of biasing resistances and temperature are also observed. Proposed power amplifier may be quite useful for transmitters and other analog communication circuits.
