Samenvatting

This paper presents a low-voltage low-power pipelined ADC with 1V supply voltage in a 90nm CMOS process. A new architecture is proposed to reduce the power consumption in high-speed pipelined analog-to-digital converters (ADCs). The presented architecture utilizes a combination of two current power-reduction techniques, double sampling and amplifier sharing. To decrease the power dissipation more efficiently, the stage scaling technique has been applied to the ADC and dynamic comparators have been used in sub-ADCs. Using this approach, a 10-bit 200MSample/s pipelined ADC has been designed in a 90nm CMOS technology. HSPICE simulation results show a signal-to-noise plus distortion ratio (SNDR) of 58.5dB with a 9.375MHz, 1-VP-P,diff input signal while consuming only 30.9mW power from a 1V supply voltage.
