摘要 |
<p>A sensor 1 produces an output that changes linearly with absolute temperature. In response to the output, a reference voltage generator 13 produces reference voltages Vhigh and Vlow that change linearly with absolute temperature. A Schmidt trigger 14 compares the output signal from a sensor signal amplifier 12 with the reference voltages for performing on-off output. A sensor signal amplifier 12 with a temperature-independent amplification factor amplifies the output signal from the sensor 1 while performing offset compensation. A sensor signal processing circuit 2 is formed out of thin-film silicon disposed on an insulating substrate. The output from the sensor 1 undergoes accurate temperature compensation over a wide temperature range from a low temperature to a high temperature, achieving a reliable operation with accuracy at high temperature. <IMAGE></p> |
