Review of Non-Isolated Inductive DC-DC Step-Up Voltage Converters for Full On-chip Integration

This paper presents a summary of the commonly used inductive voltage converters (VCs) for step-up (boost) voltage conversion with their key characteristics. Many of these topologies are based on conventional Buck and Boost converters with different alterations and/or additional components. The analysis includes current onduction modes, input source and output capacitor current stresses, and the conversion ratio under Continuous Conduction Mode (CCM) operation. The selection of VCs considered in this study was guided by the feasibility of future full on-chip integration, leading to the exclusion of topologies exhibiting excessive complexity,  requiring more than two inductors or need of transformers. This overview summarizes the key characteristics of the selected circuits and provides a guide for the further design of inductive voltage converters.
