In recent years, the function of laptop and smart phones have been improving and increasing. In this study, I focused on human detection using ultrasonic waves with MEMS microphones. Therefore, I proposed a multiple state ADC that takes the appropriate mode for an audio band and ultrasonic band processing. When switching between the two modes, the number of active transistors is switched to reduce the current consumption. In addition, the circuit configuration is also changed by switching. As a result, SNR of 99.7dB for audio signal processing and low current consumption of 187uA for ultrasonic detection was achieved.
