Development of World’s Highest Power Efficiency Analog To Digital Converter by Fujitsu
In digital converters, the analog-to-digital (A/D) converters often responsible for a large share of the equipment’s total power consumption, making them an clear target for solution capable reducing power consumption. Currently, the pipelined A/D converters are mostly used in various digital devices and mobile phones. However, pipelined A/D converters include analog circuitry, which hampers the further miniaturization of the internal circuitry. Alternative to pipelined A/D converters are SAR (Successive-Approximation-Register) A/D converters, due to the fact that SAR A/D converters contrary to pipelined A/D converters do not require amplifiers plus they are compact in size and consumes less power.
