Method and system for a signal driver using capacitive feedback
Abstract:
Edge-rate control circuits and methods are implemented using a variety of arrangements and methods. Using one such method, an output signal of a bus is controlled by decoupling a feedback capacitor (116) from a gate of a transistor (108) using an isolation switch (106). The transistor (108) is used to control the output signal. A predetermined amount of charge is removed from the feedback capacitor (116) using a charge distribution capacitor (114) that is selectively coupled to the feedback capacitor (116) using a switch (112). The switch (112) is enabled in response to the output signal reaching an output voltage and disabled in response to the charge distribution capacitor (114) reaching a reference voltage.
