Two 8-bit analog to digital converters (ADCs) were designed for biomedical applications to achieve ultra low power dissipation in a standard 0.13mum CMOS process. Both ADCs make use of the sub-threshold region of operation of the MOSFET to achieve ultra low power dissipation and both ADCs can operate down to a supply voltage of 0.3V. Both ADCs include an offset correction circuit which significantly reduces the offset voltage as a result of process and mismatch variation. The first ADC, ICGCUADC achieves a measured energy efficiency of 10.3 pJ/cycle operating at 20 kS/s with a 0.4V supply, and achieves a measured ENOB of 7 bits and a SFDR of 53.37dB when using a 0.6V supply. The second ADC, ICGCUKAH achieves a measured energy efficiency of 8.09 pJ/cycle operating at 20 kS/s with a 0.4V supply, making it the most energy efficient ADC in the published literature to date. The attenuation capacitor is digitally tuned and enables an INL and DNL below 1 LSB, a measured ENOB of 7.54 bits and a SFDR of 62.2dB when using a 0.6V supply.
