This paper shows the benefits of a sub-10 A wake-up receiver circuit used for wireless data reception with reaction times down to 60 ms. The wake-up receiver is a wireless receiver which continuously scans the radio channel for particular pseudonoise sequences. Having received and decoded the sequence, the wake-up receiver triggers different actions in smart objects. The wake-up receiver offers a scalable current consumption between 2.4 A and 99 A and is very suitable for mobile battery-operated smart objects. Details on correlation codes and two proposed protocol schemes for radio channels with bit error rates above 10% are described.
