### Closed: Re: Import pspice .cir file into cadence

Show me netlist for spectre.

Importing as schematic is not needed at all.
Use spice netlist directly, since spectre can read spice netlist.

### Closed: Re: Excessive space needed for Transient analysis Cadence

There is no simulator whose name is ADEL.

Understand things correctly, before posting.
Can you understand netlist surely ?

Show me simulator name and netlist.

dy(x)/dx=f(x)

dy1(x)/dx=f(x)
dy2(x)/dx=f(x)

d{a1*y1(x)+a2*y2(x)}=(a1+a2)*f(x)

### Closed: Re: Confused about linear vs non linear DE

Sorry, Im wrong.

Assume two solutions, y1(x) and y2(x).

y3(x)=a1*y1(x)+a2*y2(x) also satisfies y3(x)=dy3(x)/dx

You have to apply modulated signal for evaluation of ACLR, use envelope analysis which is time variable HB.

Yes for standard case.
If you have an interest about IM5 in addition to IM3, you have to reduce delta_f.

### Closed: Re: Two tone nonlinear simulation in ADS

What analysis do you use ?
HB or Tran ?

f0=(3.4GHz+3.6GHz)/2=3.5GHz
BW=0.2GHz, BW/3=0.0666GHz
I choose delta_f=50MHz < BW/3

(1) standard case
f1=f0-delta_f/2
f2=f0+delta_f/2

Set all frequencies inside bandwidth of DUT.
Where all frequencies mean f1, f2, 2*f1-f2, 2*f2-f1.

### Closed: Re: What range of frequency should I select for EM simulation to get S parameter?

Wrong.

For time resolution of 1nsec/10, system bandwidth is 10GHz.
In convolution, FIR has to be evaluated for delta_t less than 1nsec/10.
This means inverse FFT requires frequency range from...

Anyway function you use can not give valid value.
Error means nil for 1/tperiod in 2*3.14/tperiod.
That’s all.
