Abstract:
A duty cycle correction circuit includes a charge pump and a controller. The charge pump includes a current source, a first output, and a second output. The charge pump routes current from the current source to the first output during a positive portion of a clock, and routes current from the current source to the second output during a negative portion of the clock. The controller compares charge accumulated from the first output to charge accumulated from the second output over a plurality of clock cycles to determine which of the positive portion of the clock and the negative portion of the clock is longer. The controller also generates a digital value that indicates an amount of adjustment to apply to a duty cycle of the clock based on which of the positive portion of the clock and the negative portion of the clock is longer.

Claim (Index 7):
A clock duty cycle correction circuit comprising:\n a charge pump comprising a current source, a first current output terminal, a second current output terminal, a first clock input terminal, a second clock input terminal and a reset terminal, the charge pump being configured to: connect the current source to the first output terminal based on assertion of a clock signal at the first clock input terminal; connect the current source to the second output terminal based on assertion of an inverted version of the clock signal at the second clock input terminal; and short the first current output terminal to the second current output terminal based on assertion of a reset signal at the reset terminal; and a controller, coupled to the charge pump, to: compare charge accumulated from the first current output to charge accumulated from the second current output over a plurality of cycles of the clock signal to determine which of a positive portion of the clock signal and a negative portion of the clock signal is longer; and generate a digital value that indicates an amount of adjustment to apply to a duty cycle of the clock signal based on which of the positive portion of the clock signal and the negative portion of the clock signal is longer.
