Abstract
Current-mode techniques are used to realize improved high-frequency precision full-wave rectifiers (PFWRs). Three alternative topologies are described and compared in performance with the classical operational amplifier (op-amp)/diode PFWR. These are a new op-amp supply current-sensing PFWR, a modified classical op-amp/diode design and a novel current-mirror feedback design. The latter exhibits good DC accuracy and the best frequency response
