Precision full-wave rectification of differential voltage is achieved by transforming to current for rectification and reconversion to output voltage. One opamp serves as voltage-to-current converter and the other as rectifying current-to-current converter. Circuit is suitable for applications in which lower input impedance and lower frequency response are acceptable. Article gives design equations.-J.
