Operational-amplifier supply-current sensing is employed in the design of high-performance precision rectification. The designs presented in this paper compare favourably with conventional precision rectifier circuits both in linearity and bandwidth, and are constructed from low supply bias-current operational amplifiers and current mirrors. Application of this new rectifying technique in the design of precision peak-detector circuits is also described.

Inspec keywords: rectifying circuits; operational amplifiers; rectification; detector circuits

Other keywords: peak-detector circuits; operational amplifiers; low supply bias-current; current mirrors; precision rectification; wideband type; supply-current sensing

Subjects: Power electronics, supply and supervisory circuits; Modulators, demodulators, discriminators and mixers
