20100219842	Detection Circuit for Use in Various Types of Capacitive Transducers and a Transducer Including Such a Circuit - A detection circuit for detecting changes in capacitance. The detection circuit includes a tuned ratio circuit and an alternating current (AC) source AC-coupled to the tuned ratio circuit. The tuned ratio circuit includes first and second tuned circuits that are tuned to, or close, to the frequency of the AC source. Output circuitry is coupled between the two tuned circuits. During use as a transducer, an active capacitive transducer is inductively coupled to the first tuned circuit. Changes in the capacitance of the active capacitive transducer cause changes in the tuning of the first tuned circuit. The output circuitry generates an output signal that is a function of the difference between the tunings of the first and second tuned circuits.	09-02-2010
