1. A sensor circuit package comprising:
at least two Micro-Electro-Mechanical (MEM) structures, each of the MEM structures comprising:
a central core region including a thermal converter circuit that is configured to heat the central core region in response to a signal at an input thereof and to provide an temperature signal representing a temperature of a heated area of the central core region; and
a support structure coupled between the central core region and a bulk substrate base layer, the support structure configured to support the central core region to be thermally and mechanically isolated with respect to the bulk substrate base layer; and
an amplifier circuit configured to provide an amplifier signal at an output of the amplifier based on the output signals provided by the thermal converters of the respective MEM structures.
