  • Slew rate control device using switching capacitor
    Patent number: 8952738
    Abstract: Disclosed is a slew rate control device using a switching capacitor which includes a first capacitor that is connected to a target circuit operated in response to a clock signal, and controls a rising slope of a signal output from the target circuit when the clock signal is in a high state; a switch that is connected to the first capacitor in parallel, receives a reverse signal of the clock signal, as a control signal, and is turned on when the clock signal is in a low state; and a second capacitor that is connected to the switch in series, and controls a falling slope of the signal output from the target circuit when the clock signal is in the low state.
