A 85-dB dynamic range multibit delta-sigma ADC for ADSL-CO applications in 0.18-μm CMOS.

A 85-dB dynamic range multibit delta-sigma ADC for ADSL-CO applications in 0.18-μm CMOS.

A high-resolution multibit sigma-delta analog-to-digital converter (ADC) implemented in a 0.18-μm CMOS technology is introduced. The circuit is targeted for an asymmetrical digital subscriber line (ADSL) central-office (CO) application . An area- and power-efficient realization of a second-order sin...
