Title: Inverter PSRR.
Post by Jacki on Jun 17th, 2019, 1:51am

Hello,

   One confusion of the PSRR in the normal inverter-base amplifier. From my calculation it should be -6dB, but I see a lot of people use +6dB. From the definition of the PSRR, it is the gain from VDD to Vout divided by the signal voltage gain, if so I think the PSRR of the inverter should be -6dB. Any comments or calculation on +6dB PSRR?
   Thank you.

this issue is clear now, i think it depends on how do we define the PSRR in the expression.
