Using TL072 in my preamplifier. But my power supply swings between 1 volts in either side. ( Modifying single rail to double rail power supply using two diodes) is it because of this power supply swings that sometimes my speaker produce loud noise ??
your definition of common mode rejection ratio is wrong, Vc or Vcommon=(V1+V2)/2 not (VCC+VEE)/2. Where V1 and V2 are the + and - inputs of the op-amp. Hence Vc is only not zero when V1=V2. None of your examples can show the CMRR because your Vc is always 0. But the rest of the video on PSRR was excellent, thanks for teaching me about PSRR!

"PSRR" is ratio of change in output offset voltage to the change in power supply 🙄🙄
nice explanation, 100 likes, application oriented presentation, Super...
Thank you dear.
Hi, i'm from colombia, your video is excelent, ty
Thank you so much.
Nice explanation
Thank you

Hi Sir,
Whether pmos diff pair or nmos diff pair opamps have high PSRR
PMOS diff pair have High PSRR than NMOS diff pair
your definition of common mode rejection ratio is wrong, Vc or Vcommon=(V1+V2)/2 not (VCC+VEE)/2. Where V1 and V2 are the + and - inputs of the op-amp. Hence Vc is only not zero when V1=V2.

Very good sir 🙏🙏
Thank you
Good
Thank you.
