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. |
