Abstract

A 5-bit 500-MS/s time-domain flash ADC is presented. The proposed ADC consists of a reference resistor ladder, two voltage-to-time converter arrays, a time-domain comparator array and a digital encoder without sample-and-hold. In order to achieve low-power consumption with high conversion-speed and to enhance design reusability in terms of a highly digital implementation with more regular mask patterns, the time-domain comparison is devised in the flash ADC. The prototype has been implemented and fabricated in a standard 0.18μm CMOS technology and occupies 0.132mm 2 without pads. The measured SNDR and SFDR up to the Nyquist frequency are 26.6 and 35.1 dB, respectively. And the peak DNL and INL are measured as 0.43 LSB and 0.58 LSB, respectively. The prototype consumes 8mW with a 1.8-V supply voltage.
