Abstract: A phase interpolation circuit with a high linearity includes a first parallel circuit constituted by M phase interpolation units, and a second parallel circuit constituted by N phase interpolation units. An input terminal of the first parallel circuit is connected to a first clock input terminal and grounded via a first capacitor. An input terminal of the second parallel circuit is connected to a second clock input terminal and grounded via a second capacitor. An output terminal of the first parallel circuit and an output terminal of the second parallel circuit are connected to a clock output terminal and grounded via a zeroth capacitor. A circuit parameter of each phase interpolation unit corresponds to a target output weight respectively. The target output weight of each phase interpolation unit is determined by iteration to minimize a phase difference between all output clock signals of the phase interpolation circuit.

Abstract: The present invention relates to a method for preparing Ganoderma spore oil which is in the field of biotechnology. The method includes using Ganoderma spore powder and Ganoderma powder (obtained from grinding fruiting bodies) as raw materials, applying enzymatic Ganoderma sporoderm broken methods, one-step granulation, supercritical CO2 extraction method, as well as centrifugation and refining. The light yellow oleaginous substances obtained posses a variety of physiological functions such as strengthening immunity, protecting the liver and inhibiting tumor cell growth, etc. Ganoderma spore oil prepared with the present technology contains not only spore extracts, but also extracts from Ganoderma fruiting bodies and mycelium by CO2 supercritical extraction, with more types of triterpenoids. The inhibitory effects of Ganoderma spore oil is a onefold higher than spore oil prepared from the physical preparation of the sporoderm-broken spore.
