SENSOR CIRCUIT AND METHOD

原文（中国語）

A sensor circuit, method and apparatus are provided. A clock source may be configured to generate a clock signal. A plurality of samplers may be configured to receive a plurality of radio frequency signals and to produce, based on the clock signal, a plurality of low-frequency samples. A data analyzer may be configured to process low-resolution representations of the plurality of low-frequency samples collected over a plurality of sampling instances and process them at low or medium resolution to generate one or more data analysis metrics associated with the plurality of RF signals. The sensor circuit including samplers taking low-frequency samples, and a data analyzer processing low-resolution or medium-resolution representations of a number of samples collected over time for statistical analysis, provides power efficiency compared to known approaches that use power-hungry samplers at a high frequency.
