摘要： Examples of a signal calculator include a voltage multiplier and a time divider. The voltage multiplier copies time information corresponding to a first voltage and generates a third voltage using a second current corresponding to a second voltage during a first period corresponding to the copied time information. The time divider generates an output according to a result of comparing a voltage generated by a first current on the basis of a voltage corresponding to a first time with a second voltage corresponding to a second time.
