Abstract: A biodegradable BB pellet includes an organic material and an inorganic material. Therein, the organic material includes a main ingredient polybutylene-1,4-succinate, while the inorganic material is selected from pulvis talci powder, calcium carbonate, barium sulfate, mica powder, and zinc powder. The manufacturing method of the present invention is mixing the organic material and the inorganic material into a mixture, and processing the mixture orderly through injection molding, grinding, waxing and polishing. Thereby, the present invention is degradable by the environment and prevented from polluting environment. Also, due to the properties of better toughness, flexibility, and higher heat tolerance, the present invention is prevented from bursting to hurt other people and deforming during long-distance transportation.

Abstract: A dynamic NP-swappable body bias circuit includes a core circuit, a power switch and a body bias controller. The core circuit includes a body bias terminal. The power switch includes a body bias terminal, and connects the core circuit to an external voltage supply. The body bias controller is connected to the body bias terminals of the core circuit and the power switch so that the power switch and the core circuit are under the control of the body bias controller.
