An Area-Efficient Design Strategy for Dickson Charge Pumps on Flexible Substrate

This paper introduces a novel approach to design area-efficient Dickson charge pumps (CPs) with bootstrapped pass-transistors as charge transfer devices (CTDs). The proposed design strategy is analytically presented, and guidelines are provided to get the CP optimized parameters according to the given design specifications. Proof-of-concept is implemented on a recent TFT technology on a flexible substrate provided by PragmatIC. Post-layout simulations of the designed CP, as compared with the corresponding ideal version, results confirm the validity of the proposed strategy.
