Imec and Holst Centre present ADC with record figure of merit suited for low energy radios

At today’s International Solid State Circuit Conference, imec and Holst Centre report an ultra-low power 8 bit analog to digital convertor (ADC) consuming only 30fJ energy per conversion step. This world-class figure of merit ADC is especially suited for upcoming low energy radios in the ISM (industrial, scientific and medical) radio bands such as low-energy Bluetooth or IEEE 802.15.6 for body-area networks.
