Abstract
A clock signal polarity controlling circuit comprises a first latch comprising a clock input, a data input and an output. The data input is coupled to an output of a clock signal generator, the clock input is coupled to a reference clock signal. The clock signal polarity controlling circuit further comprises a second latch comprising a clock input, a data input and an output. The data input is coupled to the output of the first latch, the clock input is coupled to the reference clock signal. The circuit further comprises an XOR circuit comprising a first and second inputs and an output. The first and second inputs are coupled to the output of the second latch and the output of the clock signal generator respectively, and a clock signal having a polarity controlled by the reference clock signal is generated at the output of the XOR circuit.
