摘要:
A wave shaping circuit reduces slope magnitudes during increasing and decreasing voltage transitions. The wave shaping circuit includes a first switch that receives an input voltage having at least two voltage values where an input voltage transition between the at least two voltage values has a first slope magnitude; an inductor connected in series with the first switch; a second switch connected in a parallel arrangement with the first switch and the inductor; and a capacitor having a first end connected between the inductor and an output port and a second end connected to ground. When the input voltage begins the input voltage transition to a higher voltage value, the first switch turns on and the second switch turns off, such that the inductor limits current flow from the input voltage, decreasing a second slope magnitude of an output voltage transition to less than the first slope magnitude.
