This paper describes the design of a 10-bit, 25MS/s analogue-to-digital converter (ADC) suitable for digital video broadcasting over terrestrial (DVB-T) and handheld (DVB-H) systems. The ADC is based on a 4-3-3-stage pipeline architecture and employs dynamic comparators and Miller-hold sample-and-hold amplifiers for high-speed operation and low-power consumption. Simulated results in a 0.35μm CMOS process show that the converter achieves 56dB signal-to-noise ratio(SNR) and 57dB spurious-free dynamic range (SFDR). The converter input range is 2V peak-to-peak differential and the total power consumption is 27mW from a 2.8V power supply.
