Single Ended Class D Switching Amplifier using CMOS Technology

In previous research, the design of Class E Amplifier designed using Silicon Germanium Infineon BFQ790 BJT Transistor as the switching component. And it will be improving the technology to be applied on IOT (Internet of Things) transceiver with 2.4 GHz frequency hence the new research is taken. Hence in this modern world, the main goal of audio amplification in an audio system is to accurately reproduce and amplify the given input signal. And one of the biggest challenges is to have high output power with least amount of power loss as possible. Class D amplifier technology is making an increasing impact on the live sound world by offering high power with zero power dissipation and less weight than ever before. Now-a-days, portable music devices are becoming more popular with a growing demand of external sounds in portable music devices. This paper proposes a design of class D single ended switching power amplifier using BF554 BJT Transistor by CMOS technology at frequency below 2.4 GHz. The simulation from ADS (Advanced Design Systems) software shows that the amplifier gain is 4.326 dB at frequency 2 GHz. Finally this design ensures the stability factor of the class D amplifier 2.410 which is unconditionally stable. Citation: Dr. S. Selva Nidhyananthan, Saranya Devi V.
