Emitter/source degeneration is a technique used to guard against drift in transistor parameters like beta. In addition, it helps linearize the small signal output. The transfer characteristic of a BJT ...
Maintaining perfect stability through negative feedback is a basic element of electrical circuitry, but it’s been a mystery how cells could do it — until now. Mustafa Khammash’s small Lego robot is ...
Memories may be maintained in the brain through a mechanism familiar to any engineer — negative and positive feedback loops, according to researchers Sukbin Lim and Mark Goldman at the UC Davis Center ...
