Abstract

An approach for implementation of full-wave precision rectifiers in CMOS technology is presented, in which the rectification is performed in current domain while both input and output signals are voltages. The rectifier has a very simple structure and both noninverting and inverting circuits can be realized with one op-amp, two current mirrors, and six MOS transistors. The performances of the proposed rectifiers are analyzed and discussed. Extensive computer simulation and experimental results obtained with this and other types of precision rectifiers, which demonstrate many advantages of the proposed techniques over others, are presented
