Abstract: An electronic circuit includes an analog to digital converter (ADC) and a noise coupling filter. The ADC generates a digital output signal based on a first analog signal and a second analog signal. The noise coupling filter generates the second analog signal to be fed back for an input to the ADC, based on a first quantization error signal associated with converting the first analog signal to the digital output signal. The noise coupling filter performs noise shaping on a digital error signal derived from the quantization error signal and generates the second analog signal from a result of the noise shaping, using a clock in the digital domain.

Abstract: Provided are a mobile robot and a method of driving the same. A method in which the mobile robot moves along with a user includes photographing surroundings of the mobile robot, detecting the user from an image captured by the photographing, tracking a location of the user within the image as the user moves, predicting a movement direction of the user, based on a last location of the user within the image, when the tracking of the location of the user is stopped, and determining a traveling path of the mobile robot, based on the predicted movement direction of the user.
