Abstract
A transducer for generating an amplified signal in response to a stimulus. The transducer includes a sensing structure for sensing a stimulus and for generating a signal functionally related to the stimulus. An amplifier circuit, utilizing a single amplifier, amplifies the signal by a predetermined gain. Resistive elements in the amplified circuit are formed on the same substrate as the sensing structure and define the predetermined gain of the amplifier circuit. The transducer generates a signal having zero magnitude in response to zero pressure on the sensing structure and has fewer than seven resistors requiring laser trimming.
