Abstract :
This paper reviews and discusses an essence and the technology direction of ADC design from the point of view of conversion energy. Conversion energy of a high resolution ADC is reaching the theoretical limit, however there is still a large gap for a low resolution ADC. SAR ADC is the most energy efficient ADC and further energy reduction is possible to optimize the supply voltage. Conversion energy of a flash ADC can be reduced by reducing the transistor size and supply voltage. FD product is proposed to find the balance between the conversion energy and the conversion speed.
