Original Abstract

In addition to the recently proposed full-wave rectifier by Prommee et al. [25] using voltage-mode (VM) two-cell winner-takes-all (WTA) circuit, we present currentmode (CM) precision full-wave rectifier using CM two-cell WTA circuit. The popular Lazzaros CM WTA circuit has been employed for the purpose and there is no requirement of inverting the input signal as in [25]. Also, dual complimentary phases of the output current signal are available from high-output impedance terminals for explicit utilization. As compared to many recently proposed CM rectifiers using complex active devices, e.g. dual-X current conveyor or universal voltage conveyor, our circuit is very compact and requires a total of 21 transistors. SPICE simulation results of the circuit implemented using 0.35 um TSMC CMOS technology are provided which verify the workability of the proposed circuit.
