Do you mean "Linux Kernel Development" by Robert Love (Novell) or "Linux Device Drivers" by Jonathan Corbet, Alessandro Rubini, Greg Kroah-Hartman (O'reilly)?
You can refer to this thesis for some support http://ria.ua.pt/handle/10773/8717
But I believe you won't get that much increase in efficiency/output voltage after 3 stages
The configuration you have is working for me (I get a 1.08 V signal at the output)
However, you should only use the Harmonic Balance and Large-Signal S parameters solvers for this case (not AC)
Check these Matlab scripts, they have a function to calculate directly the axial ratio (if I remember correctly).

dBi is the Gain (in dB) of you antenna related to that an isotropic radiator (which.... doesn't exist in practice).
I believe you can simply consider the Gain in dB you get in HFSS as if it were in dBi.
On the other hand:
- dBm and dBW are relative to Power (not Gain)
- dBc stands for decibels...
1 and 2) are you sure about the 0.95 GHz working frequency and 3.3 Farad capacitors?
Note that your Source is working at 0.95 Hz while your HB simulation is running at 0.95 GHz
3) There is no ADS Design Guide for Voltage Doublers (that I know of)
4) If you want to know the input impedance...
You can also try to use a parasitic patch over your own to enhance the gain.

you can simply refer to this tutorial https://www.cst.com/Applications/Article/Microstrip-Patch-Array-Design and for the equations to dimensions the antennas check the book Antenna Theory by Balanis.
The results might shift a bit given the way you define the excitations on each simulator and given they use different types of solvers (HFSS uses Finite Element Method and CST uses Finite Integration Technique).
Also, the results will shift depending on the mesh definition (especially in CST if...
Hello, gupta
Your post is a little vague, still you can try and design a simple phased antenna patch array, vary the shape of the substrate to your objective and you will get some insight on the matter.
Hope this helps.
Dear all,
I am trying to design a series LC resonator with a interdigital capacitor in series with a circular planar inductor. When I simulated the S-parameters in the S11 I get the variation of the inductor and on the S22 the response of the Capacitor, and not the behavior of the resonator I...
Did you simulate and measured the circuit considering the same input power? Because if you are using Schottky diodes then their input impedance will not only vary with frequency but also with the input power available.
