Qucs touchstone import4/23/2024 ![]() ![]() ![]() Simply flip open the Pillbox’s lids and place your pills and supplements into the spacious, individual daily boxes.Set it once and the Pill box’s LED LITE-BOX Technology combined with escalating alarms will repeat its alerts every day at the same exact times to make forgetting or double/triple dosing virtually impossible. Large Letters for easy viewing will help assure proper filling. The Easy to open oversized finger tip tabs makes loading easy for even the most frail hands. With MED-Q’s Programmable Pillbox Technology, simply take the pills at the programmed times in the individual daily container which will be flashing with LITE-BOX Technology.Now you wait for your Pill Dispensers Audio/Visual reminders to alert you. The code is open source.The escalating alarm can be heard through out the home. For a free thing, it does a surprising amount, and what you are unhappy with, you have the opportunity to modify, or ask the user community to help. I regret I cannot help more on using qucs, because I am still trying it out. Use a few cycles of signal simulated in Spice option to check for distortion and suchlike if the levels are large enough to threaten non-linearity. ![]() Use S-parameters on the assumption the bias circuits are figured out, and go for the matching etc. That is why specialist companies like Modelithics sell fast equation type models. You can make subcircuit models from model equivalent circuits, but it will cause a significant slowdown when using Spice-type simulation and time domain transients to simulate. The hoops one has to jump through in getting proprietary models going in commercial simulators is often similar to the effort to attach a model, with parameters maybe adapted from other formats, to use in qucs. Qucs has most of the fast equation models for FET and Bipolar devices, so that you enter the math model parameters. I have not used it much, but for what I did do, the results are the same as when using MWO. The capabilities of qucs are listed here. Yes, you should draw your own schematic by placing intrinsic model ( of active device ) and peripheral parasitic end environmental elements around it. Instead, use a RLC model of this resistor by using s-parameters ( Broadband or Narrowband Model SPICE Model Generator of ADS or the others) and use it as model.It's more accurate and troublefree.Ī simple resistor will have an ideal resistor with a parallel capacitor and there will-may be-a series inductor if you work at very high frequencies.It's very simple to modelize a resistor. S-parameters "AC Small Signal Parameters" and they are not defined at DC !! Because the frequency is Zero at DC, that's why s-parameters can not be used at DC.Even if you use s-parameters of a resistor which a current flows through it, the simulation will be false.The simulator will make an extrapolation down to DC while HB or Transisent simulation is used and therefore simulator will not either converge or will be completely erroneous. The measurement conditions of measured s-parameters are mentioned in s-parameter datafile ( Touchstone or MDIF etc) ![]()
