Abstract
A low power wake on radio circuit detects if an RF signal is present on an input to the wake on radio circuit. An RF sense circuit supplies an RF sense signal indicating whether the RF signal is present on the input. The RF sense signal is used to incrementally turn on digital decode logic to determine if a radio transmission that is unique to the wake on radio circuit has been received. If the unique radio transmission have been received, the wake on radio circuit supplies a wakeup signal to the rest of the system.
