N2 - In this paper, a CMOS analog-to-digital converter (ADC) with a 6-bit 2GSPS at 1.8V is described. The architecture of the proposed ADC is based on a flash type ADC with interpolation technique to obtain a high-speed operation. In order to overcome the problems of high speed operation, a circuit to reduce the reference fluctuation, a resistor-based offset averaging technique, and a novel One-Zero detecting encoder are proposed. The fabricated chip with 0.18um CMOS occupies an area of 977um × 1040um and consumes 145mW at 1.8V power supply. The measured DNL is within 0.5LSB, and the measured SNDR is about 34.55dB, when the input frequency is 10MHz at 2GHz sampling frequency.
