Abstract
A differential driver circuit that suppresses current overshoot and allows current switching to proceed at near the maximum speed includes: a differential pair Qand Qhaving a tail current source I; a first buffer Qproviding a first input to the differential pair; a second buffer Qproviding a second input to the differential pair; a first current absorbing device Qcoupled to the tail current source Iand having a control node SP capacitively coupled to the first buffer Q; and a second current absorbing device Qcoupled to the tail current source Iand having a control node SM capacitively coupled to the second buffer Q
