    摘要: The method of manufacturing an inertial sensor includes: (A) disposing a first mold 120 and a second mold 125 on both surfaces of a predetermined region R in a plate-shaped membrane 110, (B) forming a mass body 130, a post 140, and an upper cap 150 through a plating process or a filling process, (C) disposing a third mold 160 on an exposed surface of the first mold 120 and the mass body 130, and (D) forming a lower cap 170 through the plating process or the filling process. Since the mass body 130 is made of metal by a plating process or a filling process, the density of the mass body 130 may be increased and the mass body 130 may be formed to have a structure of a high aspect ratio, thereby improving the sensitivity of the inertial sensor 100.

    摘要: Provided is an amplifier structure. The amplifier structure includes a delta-sigma modulator, an up converter, a power amplifier, and a band-pass filter. The delta-sigma modulator receives an IF signal to delta-sigma modulate the IF signal. The up converter up-converts a frequency of the delta-sigma modulated signal with an LO signal. The power amplifier amplifies a power of the up-converted signal. The band-pass filter filters the amplified signal of a selected band. The amplifier structure performs the delta-sigma modulation operation on an IF input signal, and thus can considerably decrease a delta-sigma modulation operation speed compared to a typical amplifier structure and moderate the specification in implementing a power amplifier.
