Design and Implementation for a High-performance Error Amplifier
Hui-kai Fu · Automation and Instrumentation · 2011
A High-performance error amplifier for PWM voltage feedback buck DC-DC converter switching was presented.This amplifier with feedback achieves wide dynamic range,eliminates the effect of noise,and greatly reduces the ripples in the output voltage of DC-DC converters.The error amplifier was designed and implemented by Chart.35m standard CMOS technology.The simulation results show that the DC-DC converter has good stability,more than 80% of the conversion efficiency,and its peak-peak amplitude of the output voltage ripples was less than 20mV.
