ULTRA LOW POWER SENSING PLATFORM WITH MULTIMODAL RADIOS

摘要

The device includes a system-on-chip (SoC). In some embodiments, the SoC includes a power supply circuit, a power management circuit coupled to the power supply circuit, a first wireless communication circuit and a second wireless communication circuit. The first wireless communication circuit is configured to receive an RF signal and is interlocked with a power supply circuit and a power management circuit. The first wireless communication circuit has a net radio frequency (RF) power gain not greater than 1 prior to at least one of downconversion of the RF signal or detection of the RF signal. The second wireless communication circuit is interlocked with the power supply circuit and the power management circuit.
