differential nonlinearity การใช้

Abstract : the paper proposes a mathematical model of a / d converter with quantizing error , nonlinearity and differential nonlinearity errors for computer simulation , and based on the model , the errors caused by voltage change , current change and phase change in the power measurement are analyzed by computer simulation for both the asynchronous and quasi - synchronous sampling algorithms
The simulation results in this thesis indicate that , its settling - time to full swing is 15ns with 3v supply , the total static power dissipation is less than 50mw , the differential nonlinearity error is 0 . 58lsb , the integral nonlinearity error is 0 . 54 lsb , spurious free dynamic range is more than 60db , and the output current can be adjusted
