AI Technical Summary

Technical Problem

Traditional switched-capacitor integrator designs cannot dynamically adjust power consumption resource allocation based on the input signal amplitude. This leads to problems such as overdriving when processing large-amplitude signals, resulting in energy waste, or underdriving when processing small-amplitude signals, affecting system accuracy.

Method used

An integrator was designed to dynamically select a second power supply with high drive capability or a first power supply with low drive capability by comparing the input signal voltage with a preset reference voltage, thereby achieving on-demand power supply and adjusting the working mode according to changes in the input signal.

Benefits of technology

It enables dynamic adjustment of the power supply based on the amplitude of the input signal, avoiding the limitations of a fixed power supply mode and improving the system's energy efficiency and accuracy.
