Digitally-Controlled Bondwire Inductor with High Quality Factor and Wide Tuning Range

Active Inductor based VCO for High Tuning Range

This paper presents a study of Active inductor based VCOs that helps in increasing the tuning range of the VCO , reduces the chip size and phase noise of the circuit. Study has been done on LC VCOs by replacing the passive inductors with the active one consisting of MOSFET. Design of circuit has been done on Orcade Capture using .18um technology.power consumption of circuit is 1.33mW with tunin...

Wide Tuning Range LC-VCO Using Variable Inductor for Reconfigurable RF Circuit

This paper presents a novel wide tuning range CMOS Voltage Controlled Oscillator (VCO). VCO uses an on-chip variable inductor as an additional variable element to extend the tuning range of VCO. The fabricated variable inductor achieves the variable range of 35%. The VCO was fabricated using 0.35 μm standard CMOS process, and can be tuned continuously from 2.13 GHz to 3.28 GHz (tuning range of ...

Isolation of high-quality RNA from a wide range of woody plants

Isolation of high-quality RNA is one of the most crucial methods in molecular biology. RNA extraction from woody plants has been problematic due to the presence of rigid and woody tissues, large amounts of polysaccharides, polyphenols and other secondary metabolites. Here we present a suitable protocol for RNA isolation from a wide range of woody plants that includes eight gymnosperms and four ...

DESIGN OF GIGAHERTZ TUNING RANGE 5GHz LC DIGITALLY CONTROLLED OSCILLATOR IN 0.18 μm CMOS

In this paper design and simulation of a 4.3 – 5.4 GHz LC digitally controlled oscillator (LC DCO) in IBM 7RF 0.18μm CMOS technology are presented. Wide gigahertz tuning range is achieved by using two LC DCOs, sharing same structure. DCO is made of one NMOS negative impedance transistor pair and LC tank, which consists of high quality inductor and two switched capacitor arrays for coarse and fi...
