Electrical circuit for sensors requiring a variety of bias voltages |
摘要 |
An electrical circuit provides a variety of stable and reliable bias voltages to accommodate the bias requirements of various sensor types. The electrical circuit comprises a programmable analog circuit capable of maintaining a plurality of programmable threshold voltages and producing a plurality of intermediary voltages. Such voltages act as an input to a differential amplifier that outputs a bias voltage within a range consistent with said programmable threshold voltages. The bias voltage is further conditioned by a conditioning amplifier that further stabilizes the bias voltage to an attached sensor.
