A novel current-mode precision full-wave rectifier for small-amplitude signal

The paper presents precision full-wave rectifier with two current conveyors, without any passive components and two diodes. The theory of the rectifier operation is described and analyzed. In the presented rectifier input signal can be only rectified, but at the same time it can also be rectified and amplified or rectified and attenuated. The current mode technique has been employed in order to provide the high-precision capability of the circuit. PSPICE program has been used to verify the proposed design of the current-mode precision full-wave rectifier.
