how much current should flow through current helpers in mixer

[jignesh_prajapati]

hi

i m designing mixer and using current helpers to reduce current through switches, so when i apply ac signal , from where this ac current should flow i mean all ac current pass through switch or partly current can flow through switch and helpers.

Your question is quite confusing. Do you try to DC-bias a balanced mixer?

yes i m trying to dc bias and using current helpers now if very small amount of current is passing through switches than how gain is increasing?
