Constructing/assembling an amplifier (Guide for beginners)

"Someday"
This is not human life, this is technology. There will always be an advancement. How could it be after 2050?
I think it's wrong to put a period.

Pero syempre sa ngayon, gaya ng sabi ni sir Tony, pwede pa rin mag try sa simulation, walang gastos eh.
For simple circuits it will still be a powerful tool, and to think you know the limitations.

someday, yes mag-improve pa sila but not to the point na alam nila kung ano yung actual circuit at parasitics ng end product. kailangan pa rin siyang i-input ng user. unless of course viable na ang mind reading computers by that time.

as per my post above, kung i-introduce yung parasitics sa simulation, closer to reality ang results. no need to wait till 2050. board traces will have lumped LC equivalents, nearby traces will have mutual inductance and coupling factor, capacitors will have ESR, etc.

ang closest to practice na simulator na ginagamit ko is HFSS dahil yung mismong PCB ang sina-simulate including dielectric and nearby surfaces.

Ano nga ba ang HFSS sir at baka mahanap natin sa net. Mganda ring merong ganyan ah.

^ hindi siya circuit simulator sir, High Frequency Structure Simulator, para siya sa antenna at iba pang structures used in RF. na-post ko na siya somewhere doon sa Simulator thread ata.

konting OT:

isang example of how close simulated results were reflected in actual: (using HFSS)



eto naman from Qucs:

hindi kaagad mapapansin pero 'yung sina-simulate dito is a diode, 'yan 'yung equivalent circuit niya when biased including parasitics (inductors and capacitors dahil sa package) including 'yung traces na impedance controlled. hidden schematics.







kaya tedious siyang gawin, kasi to get close to actual circuits, dapat isama talaga 'yung parasitics. way back few years ago, meron na akong models nito para i-input na lang din 'yung parasitics (ESL sa resistor, ESR and ESL sa capacitor, ESC and ESR sa inductor, etc.). ngayon, mas sinisipag akong ilagay lahat.

ok din makita na close 'yung simulation sa actual kasi masasabi mong mapagkakatiwalaan mo 'yung simulator. pero as always, nothing beats doing the actual circuit. sa simulation kasi, kahit na limited ang voltage rails mo kayang sumirit sa 1kV basta may tamang resonance.

Ida-download ko na sana ang version 13 sir eh.
Ano nga ba mgandang simulator na pang electronics project sir? Yung design Suite 11.0 yung skin eh.
