Analysis, Design and Optimization of Multilayer Antenna Using Wave Concept It...journalBEEI
The wave concept iterative process is a procedure used for analyses a planar circuits This method consists in generating a recursive relationship between a wave source and reflected waves from the discontinuity plane which is divided into cells. A high computational speed has been achieved by using Fast Modal Transform (FMT). In this paper we study a patch antenna and multilayer circuits, to determine the electromagnetic characteristics of these structures.

Marc Worrall, General Manager Digital Services from the TUI Group, talks about how TUI UK implements user feedback combined with analytics and usability testing, to enhance their digital customer experience. Delving into examples from successful campaigns, he’ll explain how TUI prioritizes feature updates and changes, while generating buy-in from key stakeholders.

I had to do a presentation with my dear collegue on the topic "Tourism product of TUI" and we put a lot effort on the research and visual part of the presentation. So I am sharing it in hope it will help someone :)

Reading Assignment: Sections 6.6.3, 6.6.4, 6.6.6, 5.6.6
1. Consider the circuit shown below,
(a) Find Gv (vout/vsig) for IBIAS values of 0.1, 0.2, 0.5, 1 and 1.25 mA.
(b) Why isn’t Gv a linear function of IBIAS?
(c) For IBIAS = 1mA, what is the maximum allowed value of Vsig, where vsig = Vsig*sin( t)? The circuit
must provide linear amplification.

(a) Choose the value of Re such that Gv is maximized, subject to the constraint that vbe ≤ 10mV and the
transistor stays in the active mode. What is the value of Gv?
(b) If β drops by 10%, what is the new value of Gv? All other design variables are unchanged.

5. Consider the circuit shown below,

(b) Find Rin, Rout, Avo and Gv.
(c) Repeat part (b) for the case that λ = 0.03. You will have to recalculate ro.
(d) Finally, you will consider the body effect; i.e., you will no longer assume that V B = VS but, instead,
that VB = -VSS, which is -5V in this circuit. You are given γ = 0.4V

and 2ϕF = 0.6V. You may
assume λ = 0 for simplicity. First, you need to recalculate the dc bias point. You may iteratively
solve for VS and Vt, using

and (√ √ ).
Do not iterate more than 2 or 3 times, as this should be sufficient to obtain the value of V t with less
than 10mV error. Then, redraw the small-signal model, now including the gmb current source shown
in Fig. 5.62 of the textbook. The value of gmb can be found using equations (5.110) and (5.111). You
are to calculate the value of Gv.

DUE: Monday October 19, 2015 at 2 PM (note new time!)
Please note that unless you show work in the derivations and solutions you will get no credit for the
answers. Obviously copied answers from study partners or other sources, etc., will also receive no credit.
Please do all parts of all eight problems. It is suggested that you make a copy of your homework before
turning it in in case it cannot be returned before Exam 2 (solution key will be provided).
