Abstract: An electronic device using a power design with a good power supply rejection ratio (PSRR) is shown. The electronic device includes a voltage regulator, a low dropout regulator (LDO), an application, and a feedback control path. The voltage regulator generates a system voltage. The LDO is coupled to the voltage regulator to receive the system voltage for generation of an LDO output voltage. The application is coupled to the LDO to receive the LDO output voltage. The feedback control path couples a flag signal to the voltage regulator. In response to the flag signal being asserted, the voltage regulator pulls up the system voltage. The flag signal is asserted before the load current of the application reaches a heavy load current level.

Abstract: A dropper seatpost includes an outer tube and an inner tube disposed in the outer tube and having a first oil chamber and a second oil chamber connected to the first oil chamber. A fluid chamber is provided between the top and bottom ends of the inner tube. A pressure adjustment member is disposed in the first oil chamber to push the oil from the first oil chamber to the second oil chamber. A floating piston is disposed between the second oil chamber and the fluid chamber and pushed by the oil stored in the second oil chamber to compress the high-pressure fluid stored in the fluid chamber. Thus, the present invention allows a user to conveniently adjust pressure of the high-pressure fluid. The arrangement of the first and second oil chambers does not significantly compromise the structural integrity of the inner tube, ensuring that it provides effective support.

Abstract: Source and drain formation techniques disclosed herein provide FinFETs with reduced channel resistance and reduced drain-induced barrier lowering. An exemplary three-step etch method for forming a source/drain recess in a source/drain region of a fin includes a first anisotropic etch, an isotropic etch, and a second anisotropic etch. The first anisotropic etch and the isotropic etch are tuned to define a location of a source/drain tip. A depth of the source/drain recess after the first anisotropic etch and the isotropic etch is less than a target depth. The second anisotropic etch is tuned to extend the depth of the source/drain recess to the target depth. The source/drain tip is near a top of the fin to reduce channel resistance while a bottom portion of the source/drain recess is spaced a distance from a gate footing that can minimize DIBL. The source/drain recess is filled with an epitaxial semiconductor material.
