The purpose of this research is to design a low power integrated complementary metal oxide semiconductor (CMOS) detection circuit for charge-modulated field-effect transistor (CMFET) and it is used for the detection of deoxyribonucleic acid (DNA) hybridization. With the available CMOS technology, it allows the realization of complete systems which integrate the sensing units and transducing elements in the same device. Point-of-care (POC) testing device is a device that allows anyone to operate anywhere and obtain immediate results. One of the important features of POC device is low power consumption because it is normally battery-operated. The power consumption of the proposed integrated CMOS detection circuit requires only 14.87 mW. The detection circuit will amplify the electrical signal that comes from the CMFET to a specified level in order to improve the recording characteristics of the biosensor. Self-cascode topology was used in the drain follower circuit in order to reduce the channel length modulation effect. The proposed detection circuit was designed with 0.18µm Silterra CMOS fabrication process and simulated under Cadence Simulation Tool.

Traditional surface acoustic wave touch screen causes high power consumption. The controller that needs to generate driving sound transducer voltage leads to large volume and high cost. It is difficult to become integration of the controller and small and medium size portable information terminal. So a low-power, ultra-light, small and medium size surface acoustic wave touch screen technology solution is proposed. On the touch screen set passive manned sensors and active detection circuit at the same time, the state transition of active detection circuit triggered by passive manned sensors, realize a touch of low power consumption, high precision requirements. In this paper the principal and system structure are discussed and the superiority is given.

A novel low-power edge detection circuit is presented in this work. Upon the arrival of signal falling edge, the proposed design establishes a small voltage difference between the gate and source terminals of a MOS transistor which slightly increases the MOS transistor leakage current. A current integration-based approach is used to robustly sense the current change and subsequently detect the signal falling edge. The design is suitable for ultra-low-power sensor wake-up circuits. Design guidelines for achieving optimal detection sensitivity as well as the implementation of calibration circuits for coping with process variations and mismatches are discussed in the paper. Simulation results are presented to demonstrate the performance of the proposed circuit.
