Abstract

The project proposed a configuration of CMOS
current sensing circuit with offset-current cancellation for boost
converters. This design will contrast the power and operational
sensing speed with the traditional proposed current-sensing
circuit. By eliminating the offset-current, it will improve the
current sensing performance. It can be accomplish by applying
current mirror as opposed of utilizing operational amplifier as a
voltage follower in conventional design which serves to subside
power consumption due to reducing the number of transistor.
Moreover, this proposed design also can cancel off the offsetcurrent in the traditional current sensing circuit, thus the
improvement of sensing-accuracy will accomplished. The
proposed design will be designed using 0.13µm technology and
simulation will be carried out in Mentor graphics. The dc-dc
boost converter will be set with operating frequency of 500kHz
and designed with the supply voltage of 2V.
