N2 - Electronic nose (EN) system based on an array of gas sensors and its recognition techniques have been widely investigated in recent decades. However, the integration of a portable EN system is not mature yet. We present an integrated EN system based on an array of gas sensor fabricated in our in-house foundry. A data acquisition technique based on a resistance-to-time conversion is proposed enabling to remove the need for an analog-to-digital converter enabling to reduce the power consumption and area. This ADC-free system is implemented in a multi-chip platform and enabling gas sensing and recognition functionalities. This system is compact, low cost and low power which is suitable for portable applications. Both sensing and recognition operations have been successfully demonstrated in our demo system.
