This article presents a low-power fully-differential 3.5GHz wideband complementary metal oxide semiconductor (CMOS) lownoise amplifier (LNA) based on the LC-ladder match network approach. To have low power consumption and high power gain, two commonsource stages are cascaded for reusing the bias current. To have wideband low noise figure, the gate width of the input transistor is determined fro...

This brief describes a new low-power fully differential second-order continuous-time low-pass filter for use at video frequencies. The filter uses a single active device in combination with MOSFET resistors and grounded capacitors to achieve very low-power consumption and large dynamic range. The ideal integrator is realized using an internally compensated op-amp consisting of only current mirr...

In this paper‎, ‎the existence and uniqueness of the ‎solution of a nonlinear fully fuzzy implicit integro-differential equation‎ ‎arising in the field of fluid mechanics is investigated. ‎First,‎ an equivalency lemma ‎is ‎presented ‎by‎ which the problem understudy ‎is ‎converted‎ to ‎the‎ two different forms of integral equation depending on the kind of differentiability of the solution. Then...

The aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (PDE) in the electroanalytical chemistry. The space fractional derivative is described in the Riemann-Liouville sense. In the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the Grunwald- Letnikov discretization of the Ri...

In this paper we present sufficient conditions for the existence of solutions to the periodic fourth order boundary value problem u(x) = f(x, u(x), u′(x), u′′(x), u′′′(x)) u(a) = u(b), i = 0, 1, 2, 3, for x ∈ [a, b], and f : [a, b] × R4 → R a continuous function. To the best of our knowledge it is the first time where this type of general nonlinearities is considered in fourth order equations w...

This paper presents the designing of a fully differential folded cascode operational transconductance amplifier (OTA) with common mode feedback circuit (CMFB). The designed OTA is operated in sub-threshold region to reduce the power consumption. The simulation is carried out in CADENCE environment using 150nm CMOS. The simulation result shows the DC gain of 82 dB with UGBW of 768 KHz, CMRR of 1...

A fully differential self-biased inverter-based folded cascode amplifier which uses the feedforward-regulated cascode principle is presented. A detailed small-signal analysis covering both the differential-mode and the common-mode paths of the amplifier is provided. Based on these theoretical results a design is given and transistor level simulations validate the theoretical study and also demo...

Triply differential cross sections are calculated for one-photon double ionization of neon and argon at various photon energies and electron energy sharings by using a frozen-core treatment to represent the remaining electrons of the residual ion. Angular distributions agree well with all existing experimental data, showing that in spite of its simplicity the method can treat the double ionizat...
