A 1.9 GHz (RF) down conversion mixer has been designed in a standard 0.25μ CMOS process. The local oscillator (LO) frequency is at 1.85 GHz. The mixer provides a voltage gain of 2.133 dB while drawing a current of 5.2 mA from a 2.5 V supply. The IIP3 of the mixer is 5.123 dBm and the -1dB compression is at -5.83 dBm. Detailed design process and simulation results are presented in this report.

This paper presents a design and performance analysis of tunable RF front end circuits such as RF band pass filter and VCO for multiband applications. The tunable element is an active inductor, built by MOS transistors. It is attractive due to its tunable and larger inductance values. The RF band pass filter is realized using active inductor with suitable input and output buffer stages. The tun...

This paper presents an UWB low noise amplifier (LNA) based on current reused topology to achieve low power on overall circuit in the band of 3~16GHz. Measurement of the input and output reflection coefficient S11, S22 are less than 10 dB, the maximum amplifier gain S21 gives 9.7dB, the minimum of the noise figure is 4.2dB, the measured IIP3 is 8.5dBm at 6GHz. It consumes 11mW power consumption ...

BACKGROUND Insulin-like growth factor II (IGF-II) is a fetal growth protein and an important proangiogenic factor controlled by four promoters (P), of which P2-P4 are inactive in the adult liver. Reactivation and dysregulation of IGF-IIP3 in particular is associated with the attenuation of apoptosis and increased proliferation in a number of liver cancer cell types. Its involvement in experimen...

this paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. in this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. the robust controller is designed on the basis of fractional lyapunov stability theory. furthermore, the effects of model uncertainti...

This paper presents the design and simulation of a 5GHz monolithic low-noise amplifier integrated with an active Balun. Intended to WLAN applications, the fully integrated circuit was implemented in a 0.18μm CMOS technology. The simulations, optimized to noise performance, gain and minimum differential phase and magnitude error, were performed with BSIM3 model. Circuit simulations present 23dB ...

When walking to intercept a moving target, people take an interception path that appears to anticipate the target's trajectory. According to the constant bearing strategy, the observer holds the bearing direction of the target constant based on current visual information, consistent with on-line control. Alternatively, the interception path might be based on an internal model of the target's mo...

In a recent paper on mixed-effects models for confirmatory analysis, Barr et al. (2013) offered the following guideline for testing interactions: “one should have byunit [subject or item] random slopes for any interactions where all factors comprising the interaction are within-unit; if any one factor involved in the interaction is between-unit, then the random slope associated with that intera...

Hoesch, Robert E., Daniel Weinreich, and Joseph P. Y. Kao. Localized IP3-evoked Ca 2 release activates a K current in primary vagal sensory neurons. J Neurophysiol 91: 2344–2352, 2004. First published December 10, 2003; 10.1152/jn.01008.2003. Electrophysiological and microfluorimetric techniques were used to determine whether intracellular photorelease of caged IP3, and the consequent release o...

The number of vehicles has increased significantly in recent years, which causes high density in traffic and further problems like accidents and road congestions. A solution regarding to this problem is vehicle-to-vehicle communication, where vehicles are able to communicate with their neighboring vehicles even in the absence of a central base station, to provide safer and more efficient roads ...
