Abstract
LEVEL COMPRESSION-EXPANSION systems (compandors), are widely used for reducing noise in signal transmission’ 3 2 . However, the IC realization of the log linear transformation system has been considered difficult due to the requirement for high performance PNP transistors in these circuits. A system which incorporates an equivalent PNP transistor with high performance characteristics will be described.
