Abstract :
A 12b 50 MS/s pipelined ADC based on a fully differential class-AB switched op-amp achieves low power consumption with a high differential input range of 2.4 Vp-p. The proposed input sampling network samples wideband signals exceeding the Nyquist frequency without a SHA. The prototype ADC in a 0.18 mum CMOS shows a power dissipation of 18.4 mW at 50 MS/s and 1.8 V with an active die area of 0.26 mm2.
