Abstract :
A 12-bit pipeline ADC fabricated in a 0.18-μm pure digital CMOS technology is presented. Its nominal conversion rate is 110 MS/s and the nominal supply voltage is 1.8 V. The effective number of bits is 10.4 when a 10-MHz input signal with 2VP-P signal swing is applied. The occupied silicon area is 0.86 mm2 and the power consumption equals 97 mW. A switched capacitor bias current generator scales the opamp bias currents automatically with the conversion rate, which gives scaleable power consumption and full performance of the ADC from 20 to 140 MS/s.
