A circuit that provides precision rectification low-level input signal with low temperature sensitivity is presented in this paper. It utilizes an improved second type current conveyor based around current-steering output stage and voltage biased silicon diodes, rather than more usual current mirrors. Pro posed design of the precision rectifier ensures good current transfer linearity in the range that satisfy class A of the amplifier and good voltage transfer characteristic for low level
