Abstract

A hierarchical high-level model of a high-speed flash ADC is presented. The input parameter list is extracted from a 400 MHz, 4-bit, flash ADC designed in HSPICE in a 0.35 /spl mu/m CMOS technology. A speedup in simulation time of 5000 is reported compared to the 3-bit flash ADC HSPICE simulations. The accuracy of the model is verified with HSPICE simulations and shows a good agreement.

用于数字通信前端混合信号仿真的高速闪存a /D转换器的高级建模
提出了一种高速闪存模数转换器的分层高级模型。输入参数列表是从HSPICE设计的400 MHz, 4位闪存ADC中提取的,采用0.35 /spl mu/m CMOS技术。与3位闪存ADC HSPICE模拟相比,模拟时间加快了5000倍。通过HSPICE仿真验证了该模型的准确性,结果表明该模型具有较好的一致性。
