Hi all, the below figure2 is PSRR of a bandgap reference (Vbg/Vdd).
In Figure 1

FIg2. I have taken the plot from https://picture.iczhiku.com/resource/eetop/WhkTwEqZEFFTEMBc.pdf
In Figure 1
- Could you tell what do I need to do to push that floor at low frequencies to more lower values? say -90 dB
- What do I need to do to push the high frequency behavior to higher frequencies? for ex. the constant low frequency behavior should be there till 100 MHz.
