【摘要】 数字技术的飞速发展,使得对模数转换器(ADC)的研究变得越来越重要.论文在并行模数转换器的基础上,结合内插结构设计了包括比较电路阵列、编码模块和输出锁存模块三个模块的八位模数转换器.这种新结构的八位并行内插模数转换器能更好地降低功耗和减小芯片面积;由于该模数转换器加入了抗饱和电路,提高了时钟脉冲的开关速度.利用Candence中的Spectre工具对电路进行了仿真,仿真结果表明,这种模数转换器达到了设计要求.更多还原

【Abstract】 With the rapid development of digital technology,the study of the ADC is becoming increasingly important.In this article,the 8 bit ADC used interpolation structure,based on the parallel ADC,which contained three modules: comparator array,encoding logic and output latches.This 8 bit parallel interpolation ADC is better to reduce power consumption and chip area;since we joined saturation control circuit in this ADC,the switching speed of the clock pulse is improved.We simulated this circuit with Spectre in Candence tools,the simulation results showed that the ADC achieved the design requirements.更多还原
