Synchronous demodulation circuit with precision track-and-hold and peak detecting circuit, occupant detection system comprising such circuit, corresponding demodulation and occupant detection method |
摘要 |
A synchronous demodulation circuit (100) uses a digitally controlled track-and-hold circuit (106) to capture the peak amplitude of a rectified signal. A microcontroller (108) controls the track-and-hold circuit (106). In particular, the microcontroller (108) controls a hold mode of the track-and-hold circuit (106) to capture the peak amplitude of the rectified signal. |
