Comparison of parameters of ring and LC-tank digitally controlled oscillators in 0.13 µm CMOS

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...

A New Solution to Analysis of CMOS Ring Oscillators

New equations are proposed for frequency and amplitude of a ring oscillator. The method is general enough to be used for all types of delay stages. Using exact largesignal circuit analysis, closed form equations for estimating the frequency and amplitude of a high frequency ring oscillator are derived as an example. The method takes into account the effect of various parasitic capacitors to...

assessment of deep word knowledge in elementary and advanced iranian efl learners: a comparison of selective and productive wat tasks

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
