③ 摘要
本文提出了一種關(guān)于單片機(jī)的化學(xué)氣體傳感器系統(tǒng)，其制造工藝CMOS技術(shù)結(jié)合了CMOS微處理技術(shù)。該系統(tǒng)包括金屬氧化物覆蓋（二氧化錫）微型熱板、必要的驅(qū)動器及信號調(diào)節(jié)電路。二氧化錫層的敏感操作溫度在200--350 ◦C之間，在芯片上的溫度控制器調(diào)節(jié)溫度膜高達(dá)350 ◦ C，特別帶有0.5 ◦C的加熱器設(shè)計，用來實(shí)現(xiàn)膜溫度達(dá)到350 ◦ C、供電電壓達(dá)到5伏的目的。加熱器的這種設(shè)計是為了使熱板在加熱的過程中溫度能夠均勻分布均勻受熱（最高溫度在1-2％波動）。溫度傳感器，內(nèi)外膜是良好的熱絕緣膜，它之間的的電路面積及大部分芯片在350 ◦ C膜溫度時，芯片溫度上升的最大值6 ◦ C。對數(shù)轉(zhuǎn)換器包含了測量電阻變化時二氧化錫氣體泄漏的一系列4個數(shù)量級。一個模擬硬件描述語言（AHDL）模型膜發(fā)展使模擬系統(tǒng)完整化。氣體檢測證明，試驗(yàn)中的氣體檢測濃度有所限制，二氧化碳低于1濃度和甲烷濃度低于100 。
This paper presents a monolithic chemical gas sensor system fabricated in industrial CMOS- technology combined with post-CMOS micromachining. The system comprises metal -oxide-covered (SnO2) micro-hotplates and the necessary driving and signal-conditioning circuitry. The SnO2 sensitive layer is operated at temperatures between 200 and 350◦C. The on-chip temperature controller regulates the temperature of the membrane up to 350◦C with a resolution of 0.5◦C. A special heater-design was developed in order to achieve membrane temperatures up to 350◦C with 5 V supply voltage. The heater design also ensures a homogeneous temperature distribution over the heated area of the hotplate (1–2% maximum temperature fluctuation). Temperature sensors, on- and off-membrane (near the circuitry), show an excellent thermal isolation between the heated membrane area and the circuitry-area on the bulk chip (chip temperature rises by max 6◦C at 350◦C membrane temperature). A logarithmic converter was
included to measuring the SnO2 resistance variation upon gas exposure over a range of four orders of magnitude.An Analog Hardware Description Language (AHDL) model of the membrane was developed to enable the simulations of the complete microsystem.Gas tests evidenced a detection limit below 1ppm for carbon monoxide and below 100 ppm for methane.
