Abstract
An electronic driver circuitry for an RF switch diode used in Acoustic Ink Jet Printing (AIP) systems is disclosed The electronic driver circuitry consists of a PMOS transistor and a poly resistor used to control the on/off states of the RF switch diode wherein the drive current for the RF switch diode is the same as the current in the PMOS transistor. To compensate for undesirable variations in the RF switch diode, the driver circuitry is designed such that the current in the PMOS transistor is adjusted in an opposite direction to cancel the unwanted variations.
