“…As the combined data revealed in Figure 12c, the total response time will be limited by the SP. It is expected that the response time of this detector can be further reduced by optimizing the sensing pad and the coating layer material or using iontophoresis as the H + introduction, for high speed sensing applications such as rapid DNA sequencing in the future [33].…”

In this work, we present a novel pH sensor using efficient laterally coupled structure enabled by Complementary Metal-Oxide Semiconductor (CMOS) Fin Field-Effect Transistor (FinFET) processes. This new sensor features adjustable sensitivity, wide sensing range, multi-pad sensing capability and compatibility to advanced CMOS technologies. With a self-balanced readout scheme and proposed corresponding circuit, the proposed sensor is found to be easily embedded into integrated circuits (ICs) and expanded into sensors array. To ensure the robustness of this new device, the transient response and noise analysis are performed. In addition, an embedded calibration operation scheme is implemented to prevent the proposed sensing device from the background offset from process variation, providing reliable and stable sensing results.

In this article, developments of Second Generation Current Conveyors (CCII) that are realized by based on the use of a differential amplifier (diff-amp) as a circuit building block are reviewed. The basic concepts of current conveyor are firstly outlined. One of the first CMOS-based promising techniques to implement CCII that proposed by Surakampontorn et al. is reviewed [9-11]. The applications of Surakampontorn’s CCII as basic circuit building blocks to realize analog circuits and systems and the modifications methods to provide multiple outputs CCIIs are outlined and discussed. Based on feedback mechanisms, diff-amp-based CCIIs that are designed by modified from the CCII are also outlined and discussed. In order to understand the improvement, the characteristics of the CCIIs that have been compared through simulation results by Hassanenin et al. [11] are presented. Finally, the concept of chemical current conveyor (CCCII) is also noted.
