Abstract
This paper describes the design of a 14-bit 20 Msps analog-to-digital converter (ADC), implemented in 0.18 μm CMOS technology, achieving 11.2 effective number of bits at Nyquist rate. An improved SHA-less structure and op-amp sharing technique is adopted to significantly reduce the power. The proposed ADC consumes only 166 mW under 1.8 V supply. A fast background calibration is utilized to ensure the overall ADC linearity.-
