Abstract

A wide-range current-mode pulse-width modulation circuit for current-mode controlled techniques is presented in this paper. The proposed circuit has been designed and implemented using 0.35-Â¿m CMOS 2P4M process. The core die size is around 95Ã—115 Â¿m² . The experimental results show that the variation of the output frequency within Â±0.25%. The linear range of input current is from 114 to 297 Â¿A , and corresponding duty cycle of pulse-width output is from 2.5% to 93.5%.
