Abstract
A data storage device comprises a first resistive temperature detector (RTD) and a second RTD coupled to a first voltage source. A tuning bridge coupled between the first and second RTDs and a second voltage source reduces offset between a first bias voltage across the first RTD and a second bias voltage across the second RTD. A low noise amplifier (LNA) receives the first and second bias voltages as a differential bias voltage. A modulator coupled between the first and second RTDs and the LNA modulates the differential bias voltage.
