thanks in advance.
On-chip current sensing technique for CMOS monolithic switch-mode power converters
Cheung Fai Lee; Mok, P.K.T.
Circuits and Systems, 2002. ISCAS 2002. IEEE International Symposium on
Volume 5, Issue , 2002 Page(s): V-265 - V-268 vol.5
Digital Object Identifier 10.1109/ISCAS.2002.1010691
Summary: An on-chip current sensing technique, which is suitable for monolithic switch-mode power converters, is presented in this paper. This current sensing technique has been fabricated with a standard 0.6 /spl mu/m CMOS process. Experimental results show that the switching converter can operate from 300 kHz to 1 MHz with the duty-ratio ranging from 0.2 to 1. The supply voltage of this current sensing circuit is from 3 V to 4.2 V, which is suitable for lithium ion battery applications. The discrepancy between the sensed signal and the inductor current is less than 4%, corresponding to 10 mA with load current 300 mA.
