Abstract: Telescopic amplifiers are often preferred for their large DC gain, low power dissipation and low flicker noise. On the other side, they suffer from serious problems like poor input common mode range and output swing. In this work, a simple technique to improve the input common mode range of telescopic structure is presented. To achieve this, two telescopic amplifiers using complementa...

We study the asymptotic behaviour of resistance scaling and fluctuation of resistance that give rise to flicker noise in an n-simplex lattice. We propose a simple method to calculate the resistance scaling and give a closed-form formula to calculate the exponent, βL, associated with resistance scaling, for any n. Using current cumulant method we calculate the exact noise exponent for n-simplex ...

– The current noise in a classical one-dimensional charge density wave system is studied in the weak pinning regime by solving the overdamped equation of motion numerically. At low temperatures and just above the zero-temperature depinning threshold, the power spectrum of the current noise S(f) was found to scale with frequency f as S(f) ∼ f−γ , where γ ≈ 1, suggesting the existence of flicker ...

Global position systems (GPS) receiver based on least mean square (LMS) could resist the interference by null jamming direction. Considering that existing band-limited Gaussian noise signals were easily suppressed LMS-based GPS receivers, a time domain random flicker algorithm was proposed to improve its performance. By disturbing convergence of LMS, it achieve purpose suppressing GPS. Simulati...
