Abstract
The present disclosure provides circuits and methods for generating clock-signals. An exemplary clock-signal generation circuit includes a delay buffer unit; an inverter unit coupled to the delay buffer unit; a first delay unit having a first NAND Boolean calculation sub unit, a first sub delay unit and a first level shift unit sequentially connected in serial, coupled to the inverter unit and configured for generating a first delayed clock-signal; and a second delay unit having a second NAND Boolean calculation sub unit, a second sub delay unit and a second level shift unit sequentially connected in serial, coupled to the inverter unit and configured for generating a second delayed clock signal.
