Abstract：In order to improve the performance of weighted capacitor array DAC(Digital to Analog Converter),the output function on zero condition and non-zero condition is found out through building up ideal model and state transition model of weighted capacitor array DAC.It proves the output of weighted capacitor array DAC only includes zero condition,and no relate with input.According to the frequency respond and timing respond function,a method of weighted capacitor array DAC transition rate estimation and correlation between sub-circuit RC factor and switching resistor are built up.Detail simulation results are shown in this paper to verify the method of weighted capacitor array DAC transition rate estimation.It provides the theory foundation for the application of weighted capacitor array DAC.
