i have a problem here, it should be a sin but here is what i get and the Vin is in V and Vout is in Giga-Volt, which is wrong, what should I do?

    Why do you have 470 farad (C3), 47 farad (C4) and 270 farad (C5) capacitors? Also, you're using the ideal op-amp which, AFAIK, can give you physically meaningless results (gigavolts). – Renan Nov 21 '22 at 13:59
  • is it normal to ge from Volt to Giga Volts? – Maya Nov 21 '22 at 14:52
  • what should i do instead 470 farad (C3), 47 farad (C4) and 270 farad (C5) capacitors? – Maya Nov 21 '22 at 14:52
  • 1) No, it's not normal. 2) Replace them with capacitors of correct values (I assume you want 470 uF, 47 uF and 270 uF). – Renan Nov 21 '22 at 14:53
  • still... it supposed to be a sin but it's not – Maya Nov 21 '22 at 14:55
  • what should i do when it's not normal? thank you so much for your help – Maya Nov 21 '22 at 14:56
  • "It is supposed to be a sin [sic]" but you have nothing that can generate sine waves there. To be honest, your circuit is a mess, maybe break it down in parts (power supply, filtering, amplification) with a clear input/output path will help you get it working. – Renan Nov 21 '22 at 14:58
  • idk how can i do this, it's my first time using LTSpice – Maya Nov 21 '22 at 15:01

    Is this based on another design, or are you designing this yourself? If you have a reference, it will help. – rdtsc Nov 21 '22 at 15:04
  • no, it's based on another designing, i just remaking it – Maya Nov 21 '22 at 15:05
  • @MaryamElYaagoubi do you have the original design? – Renan Nov 21 '22 at 15:25
  • yes, i do, and it's the same as the one i made but still doesn't work – Maya Nov 21 '22 at 15:27
