Good day everyone! I just would like to ask few questions.
I am currently working on boost converter with the following specifications:
Vin=1.2V Vout=2.5V Iload=130mA (Rload=19.3 ohm) switching frequency=500kHz in a TSMC65nm technology environment.
As per calculation values of my inductor and capacitor with the condition to operate in CCM mode are the following:
L=657uH but used Lfinal=900uH to make sure operate in CCM mode C=19nF but used 3uF to make a sure ripple=1%
But having confusion as I have tested and simulated my RLC which is attached herewith.
Testing results and simulation results depict a gain of -58.5dB to compensation.
My questions are:
1. Is this gain to be compensated realistic? Is it a bit large 2. If this is realistic can you suggest what type of compensation is suitable for this? Btw, I have already design a miller OTA with an gain 70.2dB, pgase>50 deg and a UGB=10MHz
that's all, thank you.
Best regard,
reann
