Title: Phase-splitter circuits

Abstract: Phase-splitter circuits making use of the properties of "long-tailed pair" configurations. Each such pair comprises first and second transistors connected to one another at their emitter electrodes and exhibiting an input impedance between their respective base electrodes. In the present circuits, a pair is driven by a signal source having relatively high source impedance between the base electrodes of the transistors.
