109:) then only one input (base, grid or gate) need be driven with signal; the shared connection will vary in voltage with half the amplitude of the input, becoming an input to the second device (which acts as a common-base (or common-grid or common-gate) amplifier). The sum of the currents in each of the collectors (or anodes or drains) will be almost constant, hence an increase in one will be matched by an equal decrease in the other, giving rise to equal, but opposite phase, voltages on the outputs. This technique was first described by O.H. Schmitt.

if the shared emitter (or cathode or source) resistor is relatively small, total current will vary with signal, and the signal will not be evenly split across both outputs, so a fraction of the first device's output will have to be fed to the second device's base or grid or gate to balance the
