Original Abstract

In this paper a precision full-wave rectifier of minimal configuration is presented. The main structure employs only single second-generation current conveyor and two diodes. It enables to process both low-voltage and low-current signals. The proposed circuit is able to rectify signals up to 500 kHz and beyond with no or small distortion. If the voltage or current biasing scheme is used the frequency range can be further extended. Using the CMOS structure of the current conveyor, the behavior of proposed full-wave rectifier has been verified by SPICE simulations. Furthermore, using the universal current conveyor UCC-N1B 0520 experimental measurements are also presented.

V článku je popsán přesný dvoucestný usměrňovač v minimální konfiguraci. Hlavní struktura se skládá pouze z jednoho proudového konvejoru druhé generace a dvou diod. Usměrňovač dovoluje zpracovávat jak napěťové tak proudové signály s nízkou amplitudou. Navržený obvod je schopen usměrňat signály s kmitočtem na 500kHz s minimálním zkterslením. Kmitočtový rozah zpracovávaného signálu je možné dále rozšířit použitím napěťového či proudového biasování. Chování navrženého usměrňače bylo nejprve ověřeno SPICE simulacemi za použití CMOS impmelentace aktivního prvku. Dále, za použití univerálního proudového konvejoru UCC-N1B 0520 bylo zapojení ověřeno i experimentálními měřeními.
