In this paper we present an 8Gbps CMOS amplitude-shift-keying (ASK) modulator in the transmitter and a 19.2mW 2Gbps CMOS pulse receiver circuits for high-speed and low-power 60GHz millimeter-wave impulse radio. High-speed ASK modulation is obtained without using DC power by turning on and off of the shunt connected short channel NMOSFET switches. The(More)
Political hunger strikes have been part of the debates on human rights in many countries around the world. This paper explores the preconditions for and motives behind hunger strikes in Turkey by conceiving the hunger strikers as a part of citizenship politics through which strikers not only express their views against certain common issues, but also(More)
Distributed vibration sensing based on phase-sensitive optical time domain reflectometry ( ϕ -OTDR) is being widely used in several applications. However, one of the main challenges in coherent detection-based ϕ -OTDR systems is the fading noise, which impacts the detection performance. In addition, typical signal averaging and differentiating techniques(More)
The pseudo millimeter wave 22-29GHz ultra-wideband (UWB) is attractive for the applications in short-range (SR) automotive radar sensors in order to contribute to significant reduction of traffic fatalities. Although CMOS is suitable for the short-range radar since processing units can be implemented in the same chip with the UWB front-end building block,(More)
Microwave Doppler radar system is utilized to sense breathing and heartbeat of human beings to monitor their vital conditions. The Doppler radar not only receives vital sign signals but also acquires different additive and unwanted waves such as the signal of the extra motion of the body, clutter and electromagnetic noise. Making a mathematical model of(More)
