Abstract
A new power reduction technique for analog-to-digital converters (ADCs) is proposed in this paper. The power reduction technique is a kind of amplifier sharing technique and it is suitable for ADCs in a wireless receiver. A test chip, which contains two ADCs, is fabricated in 90-nm 1-poly 7-metal CMOS technology. The 10-bit ADC dissipates 55 mW from 1.2-V supply, when the ADC operates at 200 mega-samples per second (MSPS). The 10-bit, 200-MSPS ADCs achieve maximum differential nonlinearity (DNL) of 0.66 least significant bit (LSB), maximum integral nonlinearity (INL) of 1.00 LSB, a spurious-free dynamic range (SFDR) of 66.5 dB and a peak signal-to-noise plus distortion ratio (SNDR) of 54.4 dB that corresponds to 8.7 effective number of bits (ENOB). The active area is 1.8 mm times 1.4 mm
