Abstract
In addition to the recently proposed full-wave rectifier by Prommee et al. using voltage-mode (VM)two-cell winner-takes-all (WTA) circuit, we present current-mode (CM) precision full-wave rectifier using CM two-cell WTA circuit. The popular Lazzaro’s CM WTA circuit has been employed for the purpose and there is no requirement of inverting the input signal. 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.
