A thermistor amplifier device comprising a first amplifier and a second amplifier is provided. The first amplifier generates an analog temperature signal output based on a voltage across at least one thermistor. The second amplifier generates an offset voltage input to the first amplifier, wherein the offset voltage is based on maintaining the analog temperature signal within a predefined voltage range. The second amplifier selects the offset voltage corresponding to one of a plurality of range levels, wherein each of the plurality of range levels is associated with a temperature range of the at least one thermistor.

High resolution measurement of thermistor thermometry signals with wide  dynamic range

An apparatus for electrically shielding electronic components is provided. The apparatus includes a circuit board having a first surface with a plurality of electronic components mounted on the first surface, the first surface having a first region and a second region. The circuit board comprises a ground plane and a trace on the first surface coupled to at least one electronic component in the first region and coupled to at least one electronic component in the second region. The circuit board also comprising a strip of conductive material on the first surface, the strip of conductive material forming a perimeter around the first region of the circuit board, the strip of conductive material coupled to the ground plane, the strip of conductive material defining at least one gap wherein the trace is oriented through the at least one gap. Additionally, a first filtering device is coupled to the trace on a first side of the gap. The apparatus also includes a cover composed of a conductive material for the first region of the circuit board. The cover comprises a contact surface configured to contact the strip of conductive material on the circuit board. The contact surface has at least one notch. The at least one gap of the circuit board is configured to align with the at least one notch of the cover when the cover is installed on the circuit board.
