i am designing an amplifier with p-diff input. but the input CMR of which is too narrow. how can i increase the range, especially increasing its ICMR to 0v?
i think that the Vds of the loads of the different input pairs prevent the ICMR from reaching 0v. i have increased the W/L of the loads in order to reduce the Vds, but the results is not obvious. can you give me some advice? what is wrong with my design? :(
