Digital driver with RC tuned transition control
Abstract:
Improved digital driver with transition time control of an output stage output transistor of the digital driver. A predriver circuit has a resistor that forms an RC time constant with a feedback capacitor of the output transistor. The RC time constant is adjusted to control corner resolution of the output transistor in output switching. The RC time constant can be controlled by a digitally-controlled variable capacitor. Additionally, a delay may be introduced in the turning on of the output transistor as compared with the turn off time to reduce simultaneous conduction or shoot-through current.
