<p>A pair of electrodes (I, Io) perform both input and keep-alive functions in a plasma charge transfer device (30). The input-keep alive electrodes (I, Io) are formed on opposite walls (16) of the device adjacent an array of transfer electrodes (14) and are capacitively coupled to the ionization gas. Repetitive and selective voltage pulses are multiplexed to the input-keep alive electrodes (I, Io) and synchronized with transfer electrodes pulsing, to provide, respectively, a keep-alive function and the selective input of data to the charge transfer device (30). A pair of erase electrodes (E, Eo) may also be capacitively coupled to the gas. A pulsing technique is described for restoring charge neutrality to the input-keep alive electrodes (I, Io) and erase electrodes (E, Eo) after each input or erase function. </p> |
