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 () from a gate of a transistor () using an isolation switch (). The transistor () is used to control the output signal. A predetermined amount of charge is removed from the feedback capacitor () using a charge distribution capacitor () that is selectively coupled to the feedback capacitor () using a switch (). The switch () is enabled in response to the output signal reaching an output voltage and disabled in response to the charge distribution capacitor () reaching a reference voltage.
