Distributed electrode switching device is an important part of high density resistivity instrument, and its performance will directly affect the usage of high density resistivity instrument in field work. This thesis introduces a design method of distributed electrode switching device. The device utilizes MCU to control magnetic latching relays to switch, and thus controls electrodes to switch automatically. It also utilizes RS485 chips to complete communication with adjoining electrode switching circuits. In order to test the device, this thesis introduces a software design method and the device turns out to be low power, small size and high reliable.

The objective of this chapter is to describe the various designed arithmetic circuit for an application of multimedia circuit that can be used in a high-performance or mobile microprocessor with a particular set of optimisation criteria. The aim of this chapter is to describe the design method of binary arithmetic especially using by CMOS and Pass Transistor Logic technique. The pass transistor techniques are reduced the noise margin for small circuit, which can be explained in this chapter. This chapter further describe the types of arithmetic and its techniques. The technique design principle procedure should make the following decisions: circuit family (complementary static CMOS, pass-transistor, or Shannon Theorem based); type of arithmetic to be used. The decisions on the designed logic level significantly affect the propagation delay, area and power dissipation.

When designing printed wide-slot antennas, the shape or profile of the tuning stub is a key geometric structure that affects the impedance bandwidth of the antenna. This article introduces a new process for designing tuning stub shapes, which are the blended results of a diamond and a circle. By using different geometry shapes, the design could generate a series of bandwidths with a regular trend. Detailed investigations and analysis were conducted on some key geometry parameters to explore their impact on the impedance bandwidth of the antenna. To certify the new design method, several prototypes were simulated, developed, and measured. The experimental and simulated results showed good agreement with each other. The results indicate that by properly selecting various blended shapes, a BW range from 80.1 to 117.3% for a VSWR of less than 2 could be obtained, which provides a convenient model for a wideband antenna design.
