hi
I am doing my course project on clock and data recovery. In that in phase aquisition loop phase detector is implemented by current mode logic.The problem is when i gave phase detector error output signal to v-i converter(Differential amplifier is one of stage used for voltage to cuurent converter) it is switching in only one side (either positive or negative ).Here i am attaching the v-i converter schematic and also plots of differentail amplifier i/o charactersitics
