发明名称 READOUT CIRCUIT FOR SELF-BALANCING CAPACITOR BRIDGE
摘要 <p>A capacitive transducer and a readout circuit for processing a signal from a capacitive transducer. The readout circuit includes a high gain circuit element, two summing amplifiers and two feedback path. The high gain circuit element generates an amplified transducer signal, and the summing amplifiers sum the amplified transducer signal with a positive reference voltage and the negative reference voltage, respectively, to generate a first summation signal and a second summation signal. The feedback paths feed back the summation signals to the transducer. Output circuitry generates an output signal based on the summation signals. The high gain circuit element can be a a switched capacitor integrator. The output circuitry can generates the output signal based on the first and second summation signals.</p>
