A 10bit 1.1V 130MS/s 0.125mm2 pipeline ADC for flat-panel display applications in 65nm CMOS

This paper presents the design and implementation of a low-voltage low-power high speed pipeline analog-to-digital converter (ADC) for flat-panel display application fabricated in a standard digital 65 nm CMOS technology. The ADC does not use a dedicated sample-and-hold (S&H) stage and is built by means of the cascade of 8 pipeline stages and a 2-bit flash ADC. Operational amplifier sharing technique is applied in order to reduce power consumption. Nested cascoded miller compensation technique is used to optimize speed and power of the first and second stage. Performance of 56.5 dB SNDR at 5 MHz and 50 dB at 85 MHz input frequency is obtained at 130MS/s for full-scale. The occupied silicon area is 0.125 mm

, and the power consumption of 33 mW from a 1.1 V supply.
