Design of a 11 bit 10Ms/s pipelined A/D converter

A 11 bit 10Ms/s A/D Converter (ADC) is presented. The converter consists of a five-stage pipelined architecture and adopts the negative redundant digital correction technique to correct errors in the gain and offset. The fully differential circuitry is used to improve the power supply rejection and reduce errors resulting from the charge injection. The ADC is designed in a 0.6um CMOS technology and dissipates 50mW with a 3v power supply.
