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.

A SiC-based high-performance Intelligent Power Modules (IPM) was developed. It is a System In Package (SIP) module that consist of a half-bridge with driver. In the developed SIP IPM, the internal half-bridge is made up of UnitedSiC 35mΩ/1200V Stack-Cascode switches (UF3SC120035Z) which have low on-resistance, low gate charge, simple gate drive of VGS=0 or-5V to VGS=12V, excellent integral body diode and very low switching losses. The module operates with control voltage of 12-15V for both the low and high side switches, and a logic level input that can be 3.3V, 5V or 12V. We believe that this module will enable extremely efficient switching up to 250-400kHz, depending on topology, offering several hundred kHz even in hard-switched applications.

Integration is a key way to improve the switching frequency and power density for a DC-DC converter. A monolithic integrated GaN based DC-DC buck converter is realized by using a gate driver and a half-bridge power stage. The gate driver is composed of three stages (amplitude amplifier stage, level shifting stage and resistive-load amplifier stage) to amplify and modulate the driver control signal, i.e., CML (current mode logic) level of which the swing is from 1.1 to 1.8 V meaning that there is no need for an additional buffer or preamplifier for the control signal. The gate driver can provide sufficient driving capability for the power stage and improve the power density efficiently. The proposed GaN based DC-DC buck converter is implemented in the 0.25 μm depletion mode GaN-on-SiC process with a chip area of 1.7 mm × 1.3 mm, which is capable of operating at high switching frequency up to 200 MHz and possesses high power density up to 1 W/mm2 at 15 V output voltage. To the authors’ knowledge, this is the highest power density for GaN based DC-DC converter at the hundreds of megahertz range.
