Merged Two-Stage Power Converter With Soft Charging Switched-Capacitor Stage in 180 nm CMOS

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...

Design of Two Stage Ultra Low Power CMOS Operational Transconductance Amplifier (OTA) Using 180 nm Technology

This paper deals with well-defined design criteria for ultra low power two stage CMOS operational transconductance amplifiers (OTAs) with simple yet robust implementation in nm dimension. A simple design approach which allows electrical parameters to be univocally related to each circuit element and biasing values for low frequency applications is presented.The operational transconductance ampl...

A Merged-Stage High Efficiency High Power Factor HB-LED Converter without Electrolytic Capacitor

This paper introduces a merged converter topology for supplying high-brightness light-emitting diodes for lighting applications. The converter combines a boost-based power factor correction rectifier (PFC) and a resonant converter in a single-stage. In this topology both converters share the same switching components and a bulky electrolytic capacitor, existing in conventional systems, is repla...
