    Abstract: The phase node voltage or the PWM signal in an asynchronous boost converter is monitored to detect a phase node voltage ringing. When a phase node voltage ringing is detected, a detection signal is asserted to establish a bypass path to bypass the inductor of the converter. A charge bypass circuit is shunt to the inductor, and controlled by the detection signal to establish the bypass path. Due to the bypass path, the phase node voltage is maintained at a constant, and the phase node voltage radiation and input/output noise are eliminated.

    Abstract: A method for immobilizing glycoprotein is disclosed. A surface is provided. Next, a boronic acid is contacted to the surface. The boronic acid is represented as Y—R—B—(OH)2 and includes a boronic acid group (B—(OH)2), a linker R, and a functional group Y, in which the boronic acid is bonded to the surface via the functional group Y. A glycoprotein is contacted to the boronic acid, wherein two spatially adjacent hydroxyl groups of a carbohydrate chain form a boronate ester with the boronic acid group of the boronic acid to immobilize the glycoprotein. The goal of site-specific and covalent protein immobilization without interfering the binding affinity of an antibody to antigen may be thus achieved with the reaction of boronic acid and the carbohydrate chain of Fc region.
