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.

Abstract: A dielectric waveguide (DWG) may be used to identify a composition of a material that is in contact with the DWG. A radio frequency (RF) signal is transmitted into a dielectric waveguide located in contact with the material. The RF signal is received after it passes through the DWG. An insertion loss of the DWG is determined. The presence of the material may be inferred when the insertion loss exceeds a threshold value. The composition of the material may be inferred based on a correlation with the insertion loss. Alternatively, a volume of the material may be inferred based on a correlation with the insertion loss.
