g. autonomous sensor systems (Fig. 17.4.4). Therefore a periodic system wake up is implemented, controlled by an on-chip oscillator and a programmable timing network. To generate a constant output voltage of 3.3V for duty-cycled measurement tasks, the FCCs are activated after each single cell is checked for functionality and shorted by a bypass if found faulty. After check-up completion, an LDO and a reference voltage generator are switched on to power the load during one measurement event. 1 2 Recent advances in miniaturization of both electronics and MEMS devices have resulted in a considerable power reduction [1]. On the other hand, the size of power supplies for such miniaturized devices has been only marginally scaled down. Downsizing conventional batteries to wafer level causes various problems, e.g. the electrode materials or the electrolyte have to be sealed
