In this work we have investigated the impact of quantum mechanical effects on the device performance of n-type in ultra-scaled SixGe1−x nanowire transistors (NWT) for possible future applications. For the purpose of this paper SixGe1−x NWTs with different SixGe1−x molar fraction has been simulated. However, in all devices the cross-sectional area, dimensions and doping profiles are kept constant in...
In this work we have investigated the impact of quantum mechanical effects on the device performance of n-type silicon nanowire transistors (NWT) for possible future applications. For the purpose of this paper we have simulated Si NWTs with six different cross-section shapes. However for all devices the cross-sectional area is kept constant in order to provide fair comparison. Additionally we have...
In this paper, a micro Pirani gauge sensor is studied in the purpose to be exploited for multifunction. Based on the gauge's experimental results, an adequate conditioning circuit and a single configurable CMOS readout have been proposed allowing exploiting the gauge in an original way for multi measurements. Furthermore, the proposed readout is designed in such a way that it offers the possibility...
This paper reports a novel concept of vertically stacked-spiral RF inductor with integrated nano-powder-magnetic-core in standard CMOS. Prototype inductors in a foundry 0.18µm 6-metal CMOS and a post-CMOS backend process module (i.e., CMOS+) are fabricated and measured. Result shows the proof-of-concept designs greatly increase the inductance, L, by up to 34% and the factor, Q, by 62% over a multi-GHz...
Analog-to-digital conversion plays an essential role in all kinds of electronics systems, including signal processing, communications and storage. In particular, interpolated flash ADC has been widely used in high-speed systems requiring very high sampling speed. Obviously, practical ADC design is very challenging, which has been dominated by experiences and trial-and-error skills. This is true to...
This paper presents a new impulse based ultra-wide band (UWB) transceiver system designed in 90nm CMOS technology for UWB medical radar sensing and communication applications. The design is targeting for human heart motion detection and short range data communications. The transmitter is composed of a simple on-off keying (OOK) modulated impulse generator and a variable gain-controlled amplifier (VGA)...
This paper reviews advances in new 3D electro-thermal modeling technique for ESD (electrostatic discharge) protection structures. New 3D ESD device modeling is critical to full-chip ESD protection circuit design synthesis, verification, optimization and prediction, especially for IC designs in sub 100 nm CMOS technologies.
