Current-mode square-wave converter with current-rectifying function employing MOCCII

This paper proposed a novel tunable current-mode square-wave converter with current-rectifying function. The converter has a concise and simple structure without using any passive devices, and all the active devices of the converter are grounded, which makes it convenient for IC application. The proposed converter can generate both positive and negative square-wave signals whose amplitude can be adjusted independently by the bias ports. Also it can produce positive half-wave, negative half-wave, positive full-wave, and negative full-wave rectifying current outputs. The PSPICE simulation results of the converter based on 0.25μm CMOS process are presented. The results show that the analysis method is valid and effective.
