Thank you for the reply.
But. most of the papers or articles indicates they tune each coil in the 4 coil wireless power transfer system to have a self resonance frequency in here it is 13.56 MHz, What you have mentioned about the entire system is correct abt tuning by adjusting the coupling...
Thanks for the clarification.
What I am designing here is a 4 coil wireless power transmission system, the source and load coils are single turns and Tx and Rx coils are multi-turn coils as you said, I have to design the system such that it resonates at 13.56 MHz. for the optimization i have...
Thank you for your kind reply,
But I was trying to design the antenna based on a paper published in Progress In Electromagnetics Research, Vol. 138, 197-209, 2013 : LOOP SWITCHING TECHNIQUE FOR WIRELESS POWER TRANSFER USING MAGNETIC RESONANCE COUPLING.
Pls go through the attached image of the...
hi
I am working on similar topic as you are, my work is design of four coil resonator for wireless power transmission. but i am confused how to provide the excitation for the helical structure, I have a source coil-1 turn, transmitter coil 4-turns, receiver coil 4-turns and a load coil...
Re: can esd performance be simulated
This suggestion was valuable indeed, but i was looking for something more of an explanation for my work if possible.
I am using Dongubu hi-tek foundry for my design, this foundry provides the ESD components with snap-back characteristics. If in this case...
Hi,
I am new to the design and layout of on chip ESD circuits, I heard about the simulation of non-snap back mode ESD components are posible using SPECTRE and snap-back mode ESD components are not possible using SPECTRE and needs other simulators to get the result. Is this due to the lack of...
I mentioned that i designed for 13.56MHz but i am getting the simulation result around 500Mhz and the simulation shows no variation if i change the capacitance also.
hi,
I have designed a single turn coil radius=10cm and thickness 5mm, I need to find the resonance frequency of the coil using hfss
the theoretical calculated inductance is .464 uH and for the coil to resonate at 13.56 MHz approximately i need to add a lumped capacitance of value 330pF.
I...
Re: antenna helice
Hi,
Thank you for the example.
but could you please attach any tutorial for this design, since i am not sure about how to provide the boundaries and excitation and the radiation strategy, for a new design of a helical antennae.
my antennae dimensions are 5 turns, 5mm...
Re: HFSS help needed
I tried drawing the helix but the object when selected and trying to draw the helix, the helix option is passive and not working could you please help me to sort this issue
Hi,
Could anyone help me out to plot the linear range of a single ended OTA, I mean the test bench to plot the input differential voltage V/s the output current.
I am trying to plot the curves but I guess my test-bench is wrong.
Pls help me out
thanks for the reply, but i was interested in knowing the error in the highlighted RED characters which occurs due to the setting of capacitors initial condition.
Hi,
I am working on the design of a charging circuit, where i have to increase the transistor width to almost 5000 um for allowing the current to be 500mA, but when i increase the
size of the transistor an error of this sort comes in:
Gmin = 1 pS is large enough to noticeably affect...
