Abstract
A control circuit for controlling signal rising time and falling time is provided. The circuit includes multiple data flip-flops, multiple controllable delay circuits, and multiple current source circuits. The data flip-flops are triggered by clock signals to output a plurality of data signals. The controllable delay circuits delay the data signals, based on corresponding delay amounts, to generate a plurality of activation signals. Each of the current source circuits determines whether to output a unit current to a signal output terminal according to a level of one of the activation signals. Rising or falling time for an output signal of the signal output terminal to rise or fall to a predetermined level is determined according to a cycle time length of the clock signal and the delay amount of each of the controllable delay circuits.
