Description
Summary:This paper provides a detailed analysis of minimum power loss (MPL) and maximum power transfer (MPT) methodologies for regulated and unregulated Charge pumps (CPs). Using a modified transformer model, we show analytically that MPL and MPT can be achieved independently using switching frequency and stage modulation, respectively. In contrast, MPL and MPT in regulated CP are dependent on each other, which requires an iterative approach. SPICE simulation shows that our analytical approach accurately predicts the MPL and MPT points, which will help researchers design CPs in an accurate and fast manner.
