Current limiters using single current follower and applications to precision rectifiers

A synthesis of current limiters (CLs) using single current follower (CF) is described. The breakpoint of the resulting transfer characteristic obtained from the proposed CF-based CLs is electronically adjustable through an external control current. To demonstrate feasibility of the proposed CL circuits, some non-linear applications to programmable current-mode precision full-wave rectifiers are also presented. PSPICE simulation and experimental results are included to support the theoretical claims.
