  1. Closed: Re: Why Z and Y matrices must be pure imaginary for reciprocal lossless N-port juncti

    There is no help, since it is too easy.
    This is true for all your posts.

    Closed: Re: Resistance Flicker Noise Question

    No.
    There is no definition of res_va and ppolyf_u_1k_t.
    And res_flicker_noise is not used anywhere.

    Show me things correctly.

    No.
    Show me resistor of Globalfoundaries.
  4. Closed: Re: How to read binary stimulus file in SPECTRE in pwm format

    See spectre -h vsource
    spectre -h pattern

    BTW, can you understand PWM ?
    I don’t think your waveform is PWM.
  5. Closed: Re: How to read binary stimulus file in SPECTRE in pwm format

    Don’t put vsource in schematic.
    There is no file in vsource of type=bit.
    So include netlist description.

    BTW, how long is your bit pattern ?
  6. Closed: Re: How to read binary stimulus file in SPECTRE in pwm format

    Can you understand netlist ?
  7. Closed: Re: How to read binary stimulus file in SPECTRE in pwm format

    Use correct terminology.

    Cadence spectre does not have an ability to read any binary file.

    Can you understand "a binary file" ?

    Your file is a ascii file not binary file.
    It is a bit...

    Simply I will correct your verilog-a code.
    However I can not edit it since it is image.
    I don’ t want to input code as text from image.
  9. Closed: Re: When simulating center tapped inductor in ADS

    We don’t see parasitic capacitance at crossing point, if differential inductor is drived differentialy.
  10. Closed: Re: When simulating center tapped inductor in ADS

    See https://designers-guide.org/forum/YaBB.pl?num=1205240723#9


    R0=50
    Sdiff = (s11-s12-s21+s22)/2.0
    Zdiff = 2*R0*(1+Sdiff)/(1-Sdiff)

    freq = xval(s11)
    Ldiff = imag(Zdiff)/(2*pi*freq)

    Surely see schematics.

    Port-3 is connected to center tap.
  12. Closed: Re: When simulating center tapped inductor in ADS

    Yes.

    Closed: Re: Resistance Flicker Noise Question

    res_flicker_noise() describes only noise.

    Show me both resistor content and res_flicker_noise() as text not image.

    Description of res_flicker_noise() is not appropriate.
  14. Closed: Re: Phase detector output plot in Cadence.

    I assume you use Cadence Spectre.
    Do shooting-newton-pss Analysis with seeping phase difference of two input signals whose frequencies are same.

    It is nominal resistor.
    Polisilicon resistor which is linear.


    Even carbon resistor shows fricker noise.

    Resistors in Integrated Circuit show thermal, shot and fricker noise.
    Resistor model of Cadence Spectre have ability to generate thermal, shot and fricker noise.
    This is also true for Synopsys...

    Does your resistor model truely include colored noise ?
    Show me resistor models.
  19. Closed: Re: Phase detector output plot in Cadence.

    What do you want to mean by "in cadence" ?

    Use correct terminology.
  20. Closed: Re: Stability of a circuit and its role in design steps

    No.
    Do pure frequency domain HB Analysis without transient assist, it can converge even if your circuit is unstable.

    Probably you can not understand anything at all.

    Learn and understand HB...
  21. Closed: Re: Correction of Frequency in Arrival Direction Detection

    Correction.
    E[exp(j*2*pi*(ftx-frx)*time)] is not zero.
  22. Closed: Re: Correction of Frequency in Arrival Direction Detection

    It is a frequency compensate actually, since frequency deviation of 1MHz is evaluated.

    E[(ftx-frx)*time] is not zero.
  23. Closed: Re: Problem in using Spectrum Function in Cadence IC6.13

    Wrong.
    You can not understand spectrum() at all.

    Enter “ocnHelp ‘spectrum” in CIW.
    Or launch skill finder and then enter “spectrum”
  24. Closed: Re: Problem in using Spectrum Function in Cadence IC6.13

    Show me all arguments of spectrum().
    They are too few.
  25. Closed: Re: Problem in using Spectrum Function in Cadence IC6.13

    Why is there no Tran statement in netlist ?
    On the other hand, ocean specify Tran with stop=2.052m.

    Show me followings.
