Certain embodiments of the present invention relate to a method for manufacturing a semiconductor device, in which, when a cell capacitor of a DRAM and a capacitor element in an analog element region are mix-mounted on the same chip, the manufacturing steps can be simplified. The ramp reduces safety problems relative to drop off edges adjacent a non-repaved area, and increases the life of the pavement by providing a compacted edge. A frequency offset estimation unit is provided for GFSK-modulated signals in a first receiving section and estimates the frequency offset by averaging over a bit sequence of a trailer of a data burst.
