Abstract
A non-overlapping clock generator generating an in-phase output clock signal and a reversed-phase output clock signal which are non-overlapped with each other, includes: a first and a second XOR gates, a first and a second load transistors, which are cross coupled, and includes: a first and a second delay circuits. The first delay circuit is coupled between the in-phase output clock signal and a control terminal of the first load transistor. The second delay circuit is coupled between the reversed-phase output clock signal and a control terminal of the second load transistor. Each of the XOR gates includes at least one pass transistor logic circuit configured to execute XOR logic operation and coupled to a first control voltage. A non-overlapping period is determined according to the first control voltage and/or a first delay period of the first delay circuit and a second delay period of the second delay circuit.
