The flexibility and low leakage power enable efficient scaling of average power together with performance. This allows simultaneous optimization of the sensor system (1) for various multiplexed, both on-chip and off-chip sensor interfaces, and (2) for a wide range of available harvested energy. The architecture allows further flexibility as it can be used in regular continuous (Formula presented.) mode as well, without trading off accuracy. The ADC was implemented in a 180 nm CMOS process, on the same ASIC with a temperature sensor, pressure sensor and energy harvesting functionalities. The ADC has a nominal power consumption of (Formula presented.)W, SNDR of 68 dB and BW of 200 Hz, denoting a (Formula presented.) pJ/conv.
