Abstract
A delay generator comprises: a current source for supplying a current; a first delay portion, connected to the current source, comprising at least a plurality of inverters and a first capacitor having a first capacitance; and a second delay portion, connected to the current source, comprising at least a plurality of inverters and a second capacitor having a second capacitance, wherein the first capacitance is the same as the second capacitance, wherein the first delay portion generates a first delay by discharging of the first capacitor, wherein the second delay portion generates a second delay by charging of the second capacitor, and wherein the total delay generated by the delay generator is obtained by summation of the first delay and the second delay.
