PSO-based charge pump chip area minimization

Abstract : In this paper a solution of the well-known silicon area/performance dilemma and an energy harvesting circuit for wireless sensor nodes are presented. A PSO-based integrated circuit area optimization methodology is proposed. The study is performed on a charge pump circuit, using a 0.35μm Si-CMOS process. The PSO sizing strategy has been implemented using a Spice kernel and Matlab environment. The chip size has been reduced from 583μm2 to 179μm2 after the optimization process. Simulation results from the 0.35μm parameters are given. When driving a capacitive load of 50pF, the output-generated voltage is 4V from a 1.3V input voltage. The simulated pumping gain is 3.1.
