Abstract :
We have developed a 2-step interstage amplifying pipeline system and new circuit technologies for residue amplifiers. With these techniques, we developed a 50 Msample/s 10b CMOS ADC with a 3.3V power supply, In 0.35µm 1-poly 2-Metal ASIC process without a special analog process. This CMOS ADC measures 4.84mm2. The first test chip was fabricated to verify the new architecture and was measured. It shows good linearity of less than ±1LSB and 130mW power consumption at 50MHz sampling.
