Sensor Systems with Ultra-Low Power Consumption

Low power consumption of sensor systems is especially important for mobile applications. Minimized current consumption allows using batteries or accumulators with lower capacitance, thus enabling strong reductions in size and system costs. In addition, a power-optimized circuit design enables the use of RFID or energy harvesting.
