本文提出了一种带有微电极单元阵列的可编程 CMOS 实验室 (LoCMOS)。阵列结构适合像CMOS VLSI这样的可编程。为了提高利用率，每个微电极单元都由驱动和传感电路组成。此外，在3V电源下采用了兼容CMOS的扩展漏极MOSFET（EDMOS）。该 LoCMOS 平台由 1,800 个微电极组成，利用 EDMOS 实现液滴驱动。通过其现场可编程性，该芯片可以成功地执行所有微流体操作，即二维微电极单元阵列上的液滴移动/切割/混合。 LoCMOS 平台采用 0.35um 标准 CMOS 工艺实现，展示了微流体功能和液滴检测。测量结果显示成功实现了驱动和实时液滴位置传感。
This paper presents a programmable lab-on-CMOS (LoCMOS) with micro-electrode cell array. Array structure is suitable for programmable like CMOS VLSIs. In order to improve the utilization, each micro-electrode cell is composed of actuation and sensing circuit. In addition, a CMOS-compatible extended drain MOSFET (EDMOS) is adopted under a 3V supply. This LoCMOS platform is composed of 1,800 microelectrodes with exploiting EDMOS to enable droplet actuations. Through its field programmability, the chip can successfully perform all microfluidic operations, droplet moving/cutting/mixing on a 2-dimenional microelectrode cell array. Implemented in 0.35um standard CMOS process, the LoCMOS platform demonstrates microfluidic functions and droplet detection. Measured results show successfully for actuation and real-time droplet location sensing.
