The proposed circuits are composed of two NMOS transistors, a capacitor for coupling RF input signal, four resistors for bias, and a RF choke. The circuit is implemented due to the bias control at the two-stage power amplifier to improve the overall power added efficiency and delivers 23dBm output power at 2.4GHz. The circuit can improve the power efficiency for small RF signals. The simulation indicates that the effic
