Abstract: A method and apparatus for generating a frequency-modulated continuous wave (FMCW) signal. The apparatus may include a first oscillator configured to generate a first oscillation signal, a frequency modulator configured to generate a frequency-modulated oscillation signal from the first oscillation signal based on a sequence of control words, a frequency modulation code generator configured to generate a sequence of frequency modulation codes for generating an FMCW waveform, and a frequency multiplier configured to generate the FMCW signal by up-converting the frequency-modulated oscillation signal. The sequence of control words is generated based on the sequence of frequency modulation codes. The apparatus may include a second oscillator configured to generate a second oscillation signal, and a phase detector configured to detect a phase difference between the first oscillation signal and the second oscillation signal and generate an offset code based on the phase difference. The frequency modulator may be a digital-to-time converter.

Abstract: A device for detecting a touch input to a surface comprises at least one radar transmitter component configured to transmit electromagnetic radiation in a radio frequency spectrum. The device further comprises at least one radar receiver component configured to receive a portion of the electromagnetic radiation reflected by an object performing the touch input to the surface. The device further comprises a control module configured to receive information related to the portion of the electromagnetic radiation received by the at least one radar receiver component. The control module is further configured to detect the touch input to the surface based on the information related to the portion of the electromagnetic radiation received by the at least one radar receiver component.
