An ultra-low-power frequency synthesizer targeted for IoT devices

Frequency synthesizers are key building blocks of wireless communication devices. Before installing, they need to satisfy demanding requirements. Until now, analog PLL synthesizers have...
An added constant highlights differences in synchronization Summing a constant parameter c warps the phase α into angle θ, according to a relationship that quickly becomes intricate (top). When this operation is applied to electroencephalogram signals, it seems to more clearly reveal the differences in synchronization while either resting or imagining to move a hand and while imagining to move either the left or the right hand (bottom).

Summing a constant may help to detect synchronized brain activity

People are great at recognizing whether separate things happen all the while, for instance, if two lights flash together or not. At the point...
