Author Description

This design demonstrates that a single standard digital power supply solution for a 10-bit pipeline ADC is possible at low supply voltages in deep sub-micron CMOS technology. Measurement results show that this design is capable of sampling at 12 MS/s achieving a peak signal to noise and distortion ratio (SNDR) of 52.6dB using a 1.2V supply. It consumes only 3.3mW.The continuous trend in shrinking transistor size and reducing power supply voltage has prompted an increasing demand for low voltage analog circuit designs. A novel switched buffer switching technique in complimentary metal oxide semiconductor (CMOS) has been implemented for switched capacitor circuits in a low voltage low power 10-bit pipeline analog to digital converter (ADC) designed in 90 nanometer (nm) digital only CMOS technology with no analog enhancement.
