Low-Power Pipeline ADC for Wireless LANs.

In this paper, a 10-bit 40-MS/s analog-to-digital converter (ADC) is presented. A power consumption of 12 mW was achieved by using a time-interleaved and pipelined architecture with shared operational amplifiers. This circuit was fabricated in a 2.5-V 0.25-μm technology with metal—oxide—metal capacitors. Experimental results are within design ranges and are in good agreement with simulation data. It turns out that the proposed Nyquist-rate ADC provides a potential solution for low-power high-speed applications, e.g., wireless LANs. [ABSTRACT FROM AUTHOR]
