Abstract

In consumer video-system markets, A/D converters (ADCs) are desired to be integrated with digital signal-processing circuitry to reduce system cost and size. Operation with low supply voltage (V/sub DD/) is also desired in personal equipment. In addition, circuit techniques for low-V/sub DD/ operation are essential for ADC integration into 0.5 /spl mu/m LSIs. The first low-V/sub DD/ 10b video ADC to be published uses CMOS inverters as amplifiers in "chopper" type comparators. However, experimental results show that this type of circuit has poor noise immunity when integrated into mixed-signal LSIs. A 10b 20 Ms/s CMOS ADC with 3 V power supply and high noise immunity for integration into mixed-signal LSIs is described by the authors.<>
