説明
Frequency shift measurement circuit with high sampling rate using reciprocal method for QCM odor sensor is proposed. Although the circuit including an analog-type mixer achieved the high sampling rate, the digital mixer in place of analog one is required since all the circuits can be implemented into one chip. The proposed digital mixer helped us achieve 128ms time resolution, 8 times faster than the conventional one, without the deterioration of the frequency resolution. Then, it was found that its introduction into the gas odor visualization system enabled us to have clear image. After the successful implementation into a FPGA, its ASIC version was fabricated. The increase in the mixer performance brought us further increase in the sampling rate of the frequency shift.
