Hi,
I am trying to design a bandgap circuit. For small loads, my bandgap circuit is working fine over all corners and the bandgap voltage remains the same.
With small loads the bandgap variation with temperature is only 5mV i.e., vbg ranges from 734.5mV to 739.8mV. As the load is increased, bandgap voltage drops by a large amount and there is a huge variation in the bandgap voltage with temperature. is this because of any leakage from gate to body or Something?........kindly help me to sort out this issue.
The plots are given inthe attachments
Thanks & Regards
