Abstract: A wireless system includes a local oscillator (LO) signal generation circuit, a receiver (RX) circuit, and a calibration circuit. The LO signal generation circuit generates an LO signal according to a reference clock. The LO signal generation circuit includes an active oscillator. The active oscillator generates the reference clock, wherein the active oscillator includes at least one active component, and does not include an electromechanical resonator. The RX circuit generates a down-converted RX signal by performing down-conversion upon an RX input signal according to the LO signal. The calibration circuit generates a frequency calibration control output according to a signal characteristic of the down-converted RX signal, and outputs the frequency calibration control output to the LO signal generation circuit. The LO signal generation circuit adjusts an LO frequency of the LO signal in response to the frequency calibration control output.

Abstract: In accordance with an embodiment, a feedforward filter includes a first path, at least one second path and a signal combiner. The first path has a first translational filter, and employed for providing a first frequency response and generating a first output in response to an input signal based on the first frequency response. The at least one second path has a second translational filter and is coupled to the first path. The at least one second path is employed for providing a second frequency response that is different from the first frequency response to the input signal, and generating at least one second output in response to the input signal based on the second frequency response. The signal combiner is coupled to the first path and the second path, and employed for combining the first output and the at least one second output to generate a filtered signal.

Abstract: An object detection method includes: obtaining a first offset value and a second offset value, setting a first detection threshold value by adding the first offset value to a first reference threshold value, setting a second detection threshold value by adding the second offset value to a second reference threshold value, obtaining a detection input, and performing target detection upon the detection input according to at least the first detection threshold value and the second detection threshold value. The first offset value is different from the second offset value. The first reference threshold value is determined for detecting if at least one object with a first value of an object characteristic exists. The second reference threshold value is determined for detecting if at least one object with a second value of the object characteristic exists. The second value is different from the first value.
