Wide band Power amplifier (WPA) is play the major role in wireless communication system. To achieving the maximum frequency band of power amplifier, we used new innovative pair (CCMOS Pair). This type of amplifier is suitable for wideband applications like Wi-Fi, wireless communication, mobile communication, large signal amplifications and ZigBee etc. based on radio frequency. The designed circuit of wideband power amplifieris simulated on 180 nm cadence virtuoso tool. The simulation results show the wide bandwidth up to ZHz and flat top response with fast switching operation. Key Words: Class B Power Amplifier, CCMOS Pair, 180nm CMOS Technology. 1. INTRODUCTION The Radio Frequency Communication system has demanded with high performance parameters from last one decade. Mostly used areas for communications are 5G communication system, Wi-Fi, Biomedical fields, Milliwavecommunication, mobile communication, with fast data operationsandhigher efficiency. The power amplifier directly affects the efficiency of transmitting signals; therefore, wideband power amplifier with low cost and high efficiency is required in the advanced technology of communication system. Standardization of communication demands the durability, Integrated circuits, power conservation and better performance of building blocks of communication system. It is very complex for designers to design and develop the new technology. In last few years ago, communication can be held only with audio, but today audio and video both are required simultaneously. It has a similar importance to connect with digital world. Global positioning system in every field of transmitting and receiving signal, Mobile products, Low range Bluetooth system, satellite communication, Wire-less Local area network and some of the other advanced features will increase people interest in advanced technology and also change the lifestyle of living things. [1] The major parameters to measure the performance of power amplifier are output power, gain, power added efficiency, harmonic distortion, noise and power consumption etc. 1.1 Parameters a) Output Power Power at the output terminal of power amplifier should be high for proper communication. It is defined as the active power delivered on the output load (antenna) with fundamental frequency. Instaneous output power (Pout (ins)): Pout (ins)= Vout (t)* Iout(t)----------(1) Pout =Vo 2 (max) / 2R (Load) )----------(2) or Pout =Vo 2 (rms) / 2R (Load) )----------(3) a) Gain The gain of any system has major parameters. It is the ratio of the output power of the system and the input power of the system. This parameter is usually expressed in decibel (dB). Gain = (Pout of the system) / (Pin of the system)
