Samsung patents chip design that splits one signal to save battery

Patent drawing
Patent drawing from the official filing.

Samsung describes a circuit that uses a single oscillator to create multiple radio frequencies by splitting the signal into different phases. Instead of needing separate components for each frequency, it divides one main signal and picks specific parts of it. This approach aims to reduce the power needed to tune into different radio channels.

Why it mattersIt could lead to slightly more efficient radios in phones or other devices, though the impact on battery life may be minor for most users.

In the filing’s own words

A multiple-frequency receiver is disclosed and includes a single voltage-controlled oscillator (VCO) configured to generate an output frequency; a first division circuit configured to divide the output frequency by a first value to generate a first local oscillator (LO) frequency for a first frequency chain; and a second division circuit configured to divide the output frequency by a second value to generate a second LO frequency for a second frequency chain, wherein the first value is different than the second value.

What exactly they claim (claim 1)

1. An apparatus comprising: an oscillator configured to generate an output frequency; a frequency divider configured to divide the output frequency by N to output N divided output signals, where N is an integer greater than two, the N divided output signals being separated in phase by 360/N; and a phase selection logic configured to select two signals having consecutive phases of the N divided output signals and to output a first phase signal and a second phase signal.
