Abstract

A clock synthesizer is provided. A clock buffer is configured to store an input clock signal. A Duty Cycle Corrector (DCC) circuit is connected to the clock buffer. The DCC circuit is configured to receive the input clock signal from the clock buffer, receive a control signal, and adjust a duty cycle of the input clock signal based on the control signal. An output clock signal comprising the duty cycle corrected input clock signal is generated. The output clock signal is provided. A current source is configured to sink a clamping current to the DCC circuit.
