power switches conducting at the same time. During this 100ns non-overlap interval, the input current goes to zero. This adds a small high-frequency component to the input current waveform. This ripple current can easily be absorbed by a small input bypass capacitor 3 .3 V S u p...

t (max) time or the preset current limit in the switch. ON This prevents exceeding the switch current rating or sat- urating the inductor. At very heavy loads, the inductor current self-oscillates between this peak current limit and some lower value governed by the minimum off-time...

At the same time, external devices can also generate a corresponding signal to feed back to the human brain, thus realizing a "brain-computer interaction" [1]. It can exchange information directly between the brain and the outside world without relying on conventional methods such as human ...
