Abstract :
A simple, generalized method for steady-state analysis of charge pumps or switched-capacitor power supplies, which is intuitive yet accurate, is presented. Second order effects that were previously not considered are included. The analysis is compared with simulations and shown to be accurate. The significance of the equations for analyzing charge pumps is also discussed
