Polysilicon depletion effect

The polysilicon depletion effect is like a game of tug-of-war. Polysilicon is a type of electrical switch inside an electronic device. It comes in two parts, an N-type region and a P-type region. When electricity passes through the N-type region, it pulls the P-type region down, and vice versa. This causes the electrons in the two regions to battle each other, and this battle is called the polysilicon depletion effect. The two regions pull against each other, and eventually one side wins, causing the current to either flow or stop. This can slow down the electronic device and cause it to malfunction, so engineers try to design the device in a way that minimizes the effect.
