Abstract:This paper describes the systematic design of a high speed and high resolution CMOS Flash Analog-To-Digital Converter. A 7-bit flash ADC is implemented in cadence environment using gpdk90-nm CMOS technology with a 1.2-V analog supply voltage. The converter achieves a signal-to-(noise + distortion) ratio of 39.3574dB and signal-to-spurious-free-dynamic-range of 40.7547dB with a sampling rate of 500MHz.
