Power management design for lab-on-chip biosensors

Over the past decades, we have witnessed the growth demands of portable lab-on-chip biosensors. These lab-on-chip devices are mostly powered by battery, and intelligent power management systems are required to provide supply voltage for different functional units on biosensors (e.g. a microfluidic control system might require higher voltage than the rest working units of biosensors). In this paper, a fully integrated multiple-stage voltage multiplier is proposed to provide high-voltage power needs. The proposed design was implemented with the IBM's 0.13um CMOS process with a maximum power efficiency of 81.02% and maximum voltage conversion efficiency of 99.8% under a supply voltage of 1.2 V.
