ABSTRACT:
A method and device for driving signals over a capacitive bus is provided. The device comprises at least one input line selectively activatable for receiving an input signal having a first voltage level. A drive capacitor is positioned in series with and between each of the input lines and the capacitive bus to be driven. The drive capacitor and a capacitance of the capacitive bus forms a capacitive divider network which reduces the input signal to render an intermediate signal having a second voltage level less than the first voltage level. Each of the drive capacitors is also provided with a pre-charge input for receiving a pre-charge voltage signal when its corresponding input line is not selectively activated. At least one amplifier is provided for amplifying the intermediate signal to produce an output signal on an output line having a third voltage level which is approximately the same as the first voltage level.
