Abstract
An electronic circuit apparatus (5) for a field emission device (14) comprises a charge emission device electrically connected to a charge ballast electronic circuit (13,15). The charge ballast electronic circuit includes a capacitance device (25,26) electrically connected in series with a transistor (10,12) and electrically connected in parallel with a resistor (28,23) where the capacitance is chosen to adjust a charge emitted by the field emission device.
