Hi! I don't know how to measure Loopgain, PSRR of error amplifier. Could you give me some guide or suggestion?
What is best value for PSRR in db? how to change it?
if u r using spectre the break the loop and put the source and measure the loop gain by clicking on the ac analysis.
and for measureing the psrr put the ac source on vdd and measur the gain at the output wiill be ur psrr by vdd and do the same for vss.
if u r using the hspice then use middle brook method to measure the loop gain,
and put the ac source on vdd and measure the gain at output.
hope this helps.
