This paper presents a new compact and comprehensive design methodology for RF CMOS source degenerated cascode dual functionality low noise amplifier (LNA) and power amplifier (PA) for the IEEE 802.15.4 standard (commercially known as ZigBee). Due to the need to meet the far apart performance requirements of both the LNA and the PA, the proposed design methodology is based on simultaneous graphical visualization of the relationship between all relevant performance parameters and the corresponding design parameters. To demonstrate the effectiveness of the proposed methodology, a design example is presented. The simulated performance of the designed amplifier at 2.4 GHz satisfies both the requirements of the ZigBee LNA and PA with noise figure (NF) of 1.6 dB, input third-order intercept point (IIP3) of 6 dBm and a 1 dB compression point (P1dB) of -3.5 dBm. At the high input power of 0 dBm, the amplifier achieves 24 percent power added efficiency (PAE) with 8 dB gain and 22 mW power consumption.
