Like from the place where the water is high flowing with the low-end place it moves with the low-end place from the place where the advance guard who conveys is high. This time difference the advance guard the voltage.

Ⅰ. Introduction
1. Presentation of the country
Denmark is the smallest in size and southernmost of the Nordic countries. It is also the oldest. Located north of its only land neighbour, Germany, southwest of Sweden, and south of Norway, it is located in northern Europe. From a cultural point of view, Denmark belongs to the family of Scandinavian countries although not located on the
2.3 C-V graph
The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics
② C-V chara
4. Equipment
4.1 RCA cleaning
RCA cleaning is a series of rinsing procedure prior to experiment with Si wafer. The purpose of the RCA clean is to remove organic contaminants (such as dust particles, grease or silica gel) from the wafer surface. There are three steps to be performed. The first step is to remove organic contaminant from surface of wafer. Second step is to remove any oxide layer
A filter is widely used in overall RF system. There are many species and structures in filter. A filter seems to be simple, but there are many considerations to design filter. In this paper, we design microstrip bandpass filter which has bandwidth of 500 MHz and center frequency of 2.5 GHz. Alumina is used as substrate, and chromium is used as conductor. Final results are achieved as follows. Ins
