Abstract
A clock duty correction circuit includes a first current sourcing unit that sources a current to a current path in response to a clock signal, a first current sinking unit that sinks the current of the current path in response to the clock signal, a second current sourcing unit that sources a current to the current path in response to a delay clock signal obtained by delaying the clock signal by a predetermined time, a second current sinking unit that sinks the current of the current path in response to the delay clock signal, a current adjustment unit that adjusts an amount of the current flowing through the current path according to a voltage level of a control voltage, and a clock output unit that outputs an output clock signal having a voltage level corresponding to the amount of the current flowing through the current adjustment unit.
