Hi all. I intend to see the efficiency of a rectifier circuit design in ads. I saw that to simulate it against frequency, I can use HB simulations. But if i need to obtain the output power or the efficiency vs input power, what needs to be done. If someone can throw some light on this, it will be very helpful.
Hi! I want to design a power amplifier and I know one of the simulations which should be run is HB simulation. I have started with the test circuit of the transistor. after finishing this step I tried to run HB- simulation. But for some reasons it couldn't be converged. I don't know exactly what is the source of these errors. sometimes it complain
Hi! I want to design a push-pull power amplifier in AB class. I tried to use the test circuit of the transistor in the datasheet to get some idea about designing. I'm using ads and I draw the schematic of the test I think I should run HB-simulation. But I couldn't manage to run that. but it (...)
you have calculate your circuit Q and insert it in the smith chart utility. if your elements does not exit the Q of the circuit, you will surely can meet the bandwidth. you will know how many LC you need to have in order to meet the bandwidth..
Hi all I have design a direct conversion transmitter in ads and now I wanna use it one component(the designed circuit).

Hello Members, I have a following circuit designed in Schematic window of ads. I would like to export the design to ads Layout window for fabrication phase. Can someone kindly assist me. Awaiting your positive replies, circuit: 118215 Regards
You got 2 ports, where is the third one ??What does it mean "ports gain" ?? Sorry, have you ever designed any circuit in ads ??? ( or in any environment ) If you haven't,please start simpler ones. Go through step-by-step to learn consistantly.
116576IS this model true? No, this will not simulate correctly. Simulation is wrong if you use the wrong type of circuit models, or in your case ideal wires. The reason is that this ring resonator needs coupling to the other lines, and model-based simulation includes that coupling
You made shot connected the drain and the gate by stubs... Place DC blocking capacitors before matching circuits because short stubs make the gate and drain short circuit..
Do a EM simulation and see Input Impedance from S11 on the Smith Chart. Then design a matching circuit ( L-C or Microstrip ) to adapt this impedance to 50 Ohm..
I am doing my project regarding design of cmos power amplifier for wireless applications I do no how to find input and output impedance of the circuit in ads and also to perform impedance matching in agilent ads using inductors and capacitors for impedance matching.I am also in need of TSMC 130 nm cmos ads (...)
Calculating physical parameters can be tedious and erroneous by hand.Instead, you can use "Filter design Guide" or "Passive circuit design Guide" of ads.But if you would learn how to compute these variables , you should be adressed to textbooks.Because every filter structure has its own computation method and there isn't (...)
ads like other electronic layout design tool has a 3D circuit viewer. 112642
you should use the diode spice file, ads has some equivalent circuit, but need you input some parameters.
You need to learn how to design a circuit and how not to design a circuit. The best way to do that is design stuff, and find out the hard way that something doesn't work (expensive) or start looking at other designs, preferably ones that are done well (most of the stuff you'll find online (...)
Respected Members, I have designed a voltage multiplier/Doubler at 950 MHz (0.95 GHz)(Figure below). I am having some trouble in terms of its functionality and design. If you could clarify the following; 1. Is my circuit design appropriate/correct (i.e. simulators, lumped components, values, and rest parameters)? 2. (...)

Hi everybody. I am using TSMC 0.18 in ads for simulate my design but I don't know How to connect spiral inductor ports in my circuit? In below picture two Inductor of TSMC 0.18 and my circuit Be seen. 96908 Please Help me : 1) If I want to use INDS2_STD ,Can I connect port 3 to VDD or should it connect to GND?
Cadence design examples are very few as you said but you can inspire by some examples of ads and MWOffice.. The better is to create your own circuit based on design principles of this way, you understand the design fundementals better.
I don't have much of an idea about High impedance surfaces, But if u can show me the structure that u wish to simulate, den i can give u the steps to follow.. ads is a 2.5D simulator and is good for planar circuit design. Unless u need a MOM solution for ur 3D structure, I suggest u try HFSS which gives better results for 3D structure..!!
Greetings, is it possible to use (simulate) digital component like Flip-Flop's etc in ads agilent?
TSMC typically ships model for ads as a netlist file (in Cadence Spectre format) that is included in the ads simulation netlist at runtime. To see that file check in the circuit/models folder under the location that you installed the TSMC Process design Kit. This netlist file is just a simple text file that can be read and (...)
Hello everyone, These days I'm trying to find a way to simulate the transient performance of actual RF switches (owning rise/fall time) in ads, but I didn't figure out how to build such model. For an actual RF switch, it should contain several transistors and passive components right? I just want to find such a model or circuit containing these
It's a demo of Falstad's animated simulator. The voltage doubler is a bridge (or Greinacher) type. It has a caption saying 'Start simulation' but clicking it brings up an error message. I guess it omits a necessary step. Try going to the link below. You'll see a long list of circuits. Scroll 1/3 down the page, and you'll see 'Voltage Doubler'. Cl
I want to design a half-wave rectifier circuit and a voltage doubler circuit, both of which I need to get an equivalent impedance matching network. How can I go about, doing it in ads? Thanks in advance.
hi, I think HFSS simulate the passive model, not including active circuit. You only simulate the parts in your MMIC circuit. After then, export the S parameters to ads or other tools. hope to helpful.
I've used ads before for circuit simulation, but always from a schematic. I eventually need to be able to design a HEMT and eventually a circuit using layout, but as I have no experience with this in ads, I'd like to just learn how to use this function first. Can anybody give some pointers as to go about (...)
Schottky diodes are forward biased components and bias conditions define high frequency behaviour of the diode.That's why you should use large signal models with proper bias and HB simulation will compute frequency response of your circuit. Don't use AC or S-Parameters simulation,they will be erroneous.
hi by using passive circuit DG microstrip circuit in ads, it is possible to simulate more than one smart components? i want to add two SIRs how it ll be? if i connect 2 SIRs with coupling device how to simulate all of these.. ads design guide take only one smart component at a time.. plz help me to do that..
450 MHz would be the 45th overtone of 10MHz. Not a good idea... :) Okay, that`s right... so, what frequency would you recommend? something like 50MHz? Would be the 9th... But the real problem is that I don`t really know how to design it with such a quartz in ads. I`ve never done something like that circuit with t
