This paper presents the design of a high gain low noise amplifier operating in a bandwidth of .5014 GHz for wireless applications. High gain of 16.17dB is achieved at a frequency of 4 GHz. The Low noise amplifier is an electronic amplifier used to amplify possibly very weak signals. Its mostly placed at the front-end of a radio receiver circuit so that the effect of noise from subsequent stages of...
A high gain and low-power down conversion mixer for short range wireless applications is designed in 0.18 μm complementary metal oxide semiconductor (CMOS) technology. During the design, we have adopted current-bleeding technique and a folded Gilbert topology. The mixer is tested at two frequencies e.g., 2.4 GHz and 5.2 GHz. Simulation results revealed that under 1.8 V power supply, the proposed mixer...

Antenna size reduction is one of the major problems in wireless communication devices. For this process many design topologies have been proposed. Some of thern are capacitive loaded monopole antenna, (PIFA) planar inverted-F antenna, low profile multi element miniaturized monopole antenna (LMMMA) and Inductively Coupled Capacitively Loaded Momopole antenna (ICCLMA). The existing antenna techniques...
This work presents the design of a modified two stage operational amplifier in 0.18 μm CMOS technology. The main objective of the design is to make a trade-off between offset voltage and power consumption while maintaining rail-to-rail output swing and high phase margin. For this purpose, transistors with controlled region of operation are included to the output stage. Simulation is done in Cadence...
Operational amplifiers are an integral part of analog and mixed signal design. With the advancement of process technology, the transistor dimensions are rapidly scaling down leading to reduced ro. In deep sub-micron regime, this leads to a fairly small low frequency gain offered by amplifiers. Applications demanding high gain amplifiers suffer at design level. Even multi-stage architectures fail to...
