As a result, it is shown that increasing of tail current and LC tank quality factor decreases the phase error. Derived equations show that the phase error can be cancelled and even controlled by adjusting bias currents. To evaluate the proposed analysis and consequent designed QO, a 5.5 GHz ...
The resonance tank is aided by the parallel capacitors in proposed design, which add fixed capacitance and marginally reduce the maximum frequency. However, their main purpose is to act as a high-frequency noise filter, increasing the LC tank's quality factor (Q) and lowering thermal noise whil...

Usually, a tank water heater has a warranty of 6 to 10 years and cannot last more than 12 years. On the other hand, a tankless water heater has an average warranty of 15 years and can last up to two decades. Therefore, they are a greater investment in the long run. With that in ...
Ideally, the oscillations produced by a tank circuit continue indefinitely. However, realistically, oscillations will decay in amplitude over the course of several cycles due to the resistive and magnetic losses of the inductor. Inductors with a high-quality factor, or Q rating, will produce longer...
A novel fully integrated CMOS LC tank VCO is presented. The LC tanks are implemented by exploiting the active circuit 'boot-strapped inductor' (BSI), which behaves like a high-quality factor inductor. Particularly, the LC tanks have been implemented by introducing a new version of the CMOS BS...
The present invention refers to an integrated LC-tank structure with improved Radio-Frequency (RF) choke function and optimized geometry, which minimize area consumption and maximize quality factor. The LC-tank is based on a differential transformer and two capacitors connected in parallel with the ...
It is found that only two reduced parameters are needed to unfold the bifurcation set of this extended system: one is related to the quality factor of the LC resonant tank, and the other accounts for the balance between serial and parallel losses. Through a rigorous mathematical study, a ...
