High-level modeling of a high-speed flash A/D converter for mixed-signal simulations of digital telecommunication front-ends
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.
