Abstract:
This thesis describes the design of low noise amplifier (LNA) for the international Square Kilometre Array (SKA) project. LNAs in radio astronomy receivers play an important role of amplifying very weak signals from the Universe and the significance of the LNAs become more crucial in the SKA which is the largest and most sensitive radio telescope in the World. The aperture array (AA) system proposed for SKA is projected to deploy tens of millions of LNAs in a receiver system to survey large areas of the sky simultaneously over the frequency bands of 70-450MHz and 400-1400MHz. Hence LNA power e

The increasing demand for high data rate devices and many applications in short range high speed communication, attract many RF IC designers to work on 24-GHz transceiver design. The Federal Communication Commission (FCC) also dedicates the unlicensed 24-GHz band for industrial, science, and medical applications to overcome the interference in overcrowded communications and have higher output signal power. LNA is the first building of the receiver and is a very critical building block for the overall receiver performance. The total NF and sensitivity of the receiver mainly depends on the LNAs

A 5 GHz continuous unlicensed bandwidth is available at millimeter-wave (mm-wave) frequencies around 60 GHz and offers the prospect for multi gigabit wireless applications. The inherent atmospheric attenuation at 60 GHz due to oxygen absorption makes the frequency range ideal for short distance communication networks. For these mm-wave wireless networks, the low noise amplifier (LNA) is a critical subsystem determining the receiver performance i.e., the noise figure (NF) and receiver sensitivity.

Low Noise Amplifiers (LNAs) are one of the most important components found in some of the radio receivers used in radio astronomy. A good LNA should simultaneously possess both a gain in excess of 25\,dB and as low a noise contribution as possible. This is because the gain is used to suppress the noise contribution of the subsequent components but the noise generated by the LNA adds directly to the noise of the overall receiver.

Abstract:
Electron spin-polarized helium 2$\sp3$S$\sb1$ metastable atoms are a valuable probe of spin-dependent phenomena. Helium metastable atoms can be polarized by illumination with circularly-polarized 1.083 $\mu$m 2$\sp3$S$\sb1 \leftrightarrow$ 2$\sp3$P$\sb{0,1,2}$ resonance radiation in a process known as optical pumping. Metastable atom polarizations obtained in this manner have been limited by the low intensity of optical pumping radiation available from helium discharge lamps, until now the only practical source of 1.083 $\mu$m light. However, recent advances in the field of solid-state near-in

To achieve the desired gain and output matching, a common-source and source follower stages are used for the second and third stages, respectively. The proposed UWB LNA achieves fully on-chip circuit implementation, contributing to the realization of a single chip CMOS UWB receiver.

In low noise amplifier we used this architecture to match the input impedance while providing better noise figure. In mixer we maintain character of the Gilbert cell mixer and employed dc coupled capacitor to achieve low supply voltage. According to ADS simulation, the LNA dissipates 18mW and provides 1.8dB noise figure, 18.7dB power gain and an input 1dB compression level of —9dBm at 2.4GHz. The mixer dissipates 7.7mW,

The RF circuits are usually implemented in GaAs or Bipolar process. However, these two processes are not compatible to the typical CMOS process, which is used to implement the base band circuits. Thus, if the CMOS RF circuits can be realized, the whole receiving circuits can be integrated into a single chip, and then the cost will be cut down significantly. In order to decrease power loss, RF circuits operate at voltages at or below 1V are required. Transf
