[Retracted] Applications of Wireless Communication in a New Dual Branch CTS Charge Pump Based on Employing Clock Matched Technology

With the increase in communication requirements, new communication technologies and implementation methods have developed rapidly. The rise of emerging markets such as the Internet of Things, smart homes, smart cities, and wearables has promoted the development of wireless communication integrated circuits in the direction of monolithic, low energy consumption, and high energy efficiency. This paper proposes a new dual branch charge pump based on CTS charge pump with enhanced current drive capability and undesired charge transfer completely eliminated. Clock matched technology is proposed to completely eliminate undesired charge transfer caused by delay turn on and off of the auxiliary transistors in the traditional CTS charge pump. The current drive capability is enhanced by employing NMOS transistors with 2Vdd gate drive voltage, while traditional dual branch CTS charge pumps are based on PMOS with 1Vdd gate drive voltage. The output voltage ripple is also reduced resulting from a dual branch structure. Simulation results of output voltage gain and power efficiency for the proposed charge pump and other traditional charge pumps are provided. Comparisons are made to show the improvement of the proposed charge pump compared with other traditional charge pumps.
