Groner Samuel
 Samuel Groner was born and currently lives in Zurich, Switzerland. He has been passionate about both art and science as long as he can remember. At present he works for Weiss Engineering Ltd. in the field of analogue hardware design and freelances as classical recording engineer/producer. Besides this, he teaches several courses at a local sound engineering school (ear training, classical music production and audio measurement) and enjoys a manifold activity as pianist, singer and choirmaster. If time permits, he is found on one of the numerous Swiss hiking trails, preferably in company with one of his cameras and a few sheets of black-and-white film. He holds a MSc degree in computer science and a MA degree as Tonmeister (recording engineer/producer). |

A New Amplifier Topology With Push-Pull Transimpedance Stage
 In this article Samuel reviews existing transimpedance stage configurations, and then introduces an amplifier topology which uses a novel push-pull transimpedance topology. Compared to known standard amplifier configurations, the new circuit offers a substantial improvement in power supply rejection. Furthermore secondary slew rate limits are addressed, and sensitivity to loading from the output buffer is reduced. This makes this amplifier architecture particularly suitable for high quality audio power amplifier designs. Experimental results using model amplifiers are presented.
