Analysis of output ripple in multi-phase clocked charge pumps

چکیده
This paper presents a mathematical analysis of the ripple voltage caused by a mismatch in parasitic capacitances in multi-phase, clocked charge pumps. Through detailed circuit modeling, we show that a relatively large pedestal ripple is caused by a small mismatch in parasitic capacitance. We present a simple circuit solution and verify its performance with simulation and experimental results.

Multi-Stage DC-AC Converter Based on new DC-DC converter for energy conversion
This paper proposes a multi-stage power generation system suitable for renewable energy sources, which is composed of a DC-DC power converter and a three-phase inverter. The DC-DC power converter is a boost converter to convert the output voltage of the DC source into two voltage sources. The DC-DC converter has two switches operates like a continuous conduction mode. The input current of DC-DC...
متن کاملArea efficient CMOS charge pump circuits
This paper describes the operation of three types of charge pump circuits. Power efficiency theory of charge pumps is discussed. A method of estimating the output ripple of a charge pump from the size of the capacitors used is described. A new charge pump circuit that uses two cascoded buffer transistors to improve the area efficiency is proposed.
متن کاملEffect of charge on separation of liposomes upon stagnation
Abstract Liposomes are used widely as drug delivery systems in different forms including nanosuspensions, osmotic pumps, infusion pumps and IV injections. Some of these systems (e.g. infusion or osmotic pumps) might stay stagnant for a long time during or before administration, and therefore, might face phase separation. In spite of these, there is no data available about the behavior of lipos...

The paper analyzes different concepts for active charge balancing for a multi-cell battery energy storage system used as a backbone for a DC micro grid. The storage system is based on a cascaded multi-level converter topology where each (lead-acid) battery is equipped with dedicated low-voltage buck type DC/DC converter stage placed directly at the battery terminals. To minimize the output ripp...
