Abstract
A stylus pen is disclosed that can be used as an input device to a digitizer associated with a computer screen on a computing device, such as a computer, mobile device, tablet, etc. The stylus pen can include a voltage boost circuit that generates a stylus output signal on an antenna output. The voltage boost circuit has a charging portion and a discharging portion. Both portions have transistors that are activated and deactivated through pulsed control signals. However, a pulse duration for each control signal is separately controllable through different RC-based circuits. Additionally, the voltage boost circuit provides power savings by draining the output voltage signal to a positive voltage rail, rather than ground.
