A charge pump is a kind of DC/DC converter made up of capacitors and switches or diodes which converts an input voltage V_in to an output voltage V_out >> V_in. Capacitive charge pumps are used in applications such as micro-energy harvesting, non-volatile memories or dynamic voltage scaling.

Our capacitive charge pump simulator gets very fast and accurate results in the slow-switching limit (SSL) regime when compared to SPICE-based electrical simulators. Our simulator is based on MATLAB^&reg computing an iterative process of matrix calculations across the clock cycles of the capacitive charge pump. This simulator allows analyzing and designing Dickson (LQP), Fibonacci (FQP) and exponential (EQP) topologies, with and without charge reusing approach.
