Paper Abstract

The paper describes a design of a +200 V polarization voltage supply for condenser microphones, dedicated for use in photoacoustic applications. Due to very low signal levels, typical for photoacoustic experiments, the design was optimized towards minimum electromagnetic and acoustic emission. In addition output voltage can be digitally adjusted in a relatively wide range.
