The Impact

AbstractThe impact of technology scaling on the MOS transistor performance is studied over a wide range of dielectric permittivities using two-dimensional (2-D) device simulations. It is found that the device short channel performance is degraded with increase in the dielectric permittivity due to an increase in dielectric physical thickness to channel length ratio. For Kgate greater than Ksi, we observe a substantial coupling between source and drain regions through the gate dielectric. We provide extensive 2-D device simulation results to prove this point. Since much of the coupling between source and drain occurs through the gate dielectric, it is observed that the overlap length is an important parameter for optimizing DC performance in the short channel MOS transistors. The effect of stacked gate dielectric and spacer dielectric on the MOS transistor performance is also studied to substantiate the above observations.

Detection Circuit

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.

Cmos Voltage Reference

A novel low-voltage low-power CMOS voltage reference independent of temperature is presented in this design. After considering the combined effect of (1) a perfect suppression of the temperature dependence of mobility; (2) the compensation of the channel length modulation effect on the temperature coefficient, a temperature coefficient of 10 ppm/[Formula: see text]C is achieved. Moreover, by adopting the subthreshold MOSFETs, there are no resistors used in the proposed structure. Therefore, the maximum supply current measured at the maximum supply voltage is 70 nA and at 80[Formula: see text]C. The circuit can be used as a voltage reference for high performance and low power dissipation on a single chip.
