چکیده

This review highlights various design and realization aspects of three commonly used charge pump topologies, namely, the linear, exponential, and the Fibonacci type of charge pumps. We shall outline the new methods developed recently for analyzing the steady and dynamic performances of these circuits. Some practical issues for the CMOS implementation of these charge pump structures will be critically discussed. Finally, some conventional voltage regulation methods for maintaining a stable output under a large range of loading current and supply voltage fluctuations will be proposed.

Analytical and Practical Analysis of Switched-Capacitor DC-DC Converters

Switched-capacitor DC-DC converters are useful alternatives to inductor-based converters in many lowpower and medium-power applications. This work develops a straightforward analysis method to determine a switched-capacitor converter’s output impedance (a measure of performance and power loss). This resistive impedance is a function of frequency and has two asymptotic limits, one corresponding ...

Semi-custom VLSI Design and Realization of DC-DC Converters in UMC90

As CMOS technology is scaling down, the effect of voltage drop in power distribution network is becoming more prominent. Such voltage drops on power lines in a clock network introduces significant amount of skew, thereby degrading the signal integrity. With rising power consumption and decreasing supply voltages, the supply current will increase in future devices. The IR drops can be reduced by...

Switched-capacitor Dc-dc Converters for Low-power On-chip Applications

The paper describes switched-capacitor dc-dc converters (charge pumps) suitable for on-chip, low-power applications. The proposed configurations are based on connecting two identical but opposite-phase SC converters in parallel, thus eliminating the need for separate bootstrap gate drivers. We focus on emerging very low-power VLSI applications such as batterypowered or self-powered signal proce...

A Low-Voltage, Low-Power, Two-Stage Amplifier for Switched-Capacitor Applications in 90 nm CMOS Process

Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...
