Abstract :
This paper presents the printed circuit board (PCB) ground-parastic effects on the figure of merit of a WiMAX low noise amplifier (LNA) RFIC. The LNA RFIC is fabricated in 0.35-mum standard SiGe BiCMOS foundry process. The chip size is equal to 0.84 mm times 0.18 mm .The power consumption is 33.6 mW from the supply voltage of 3 V. The PCB ground-parasitic effects act as the source degeneration in the proposed WiMAX LNA and cause the degradation in noise figure (NF) and gain by 0.5 dB and 2.8 dB, respectively. The comparison of simulation and measurement shows good agreement.
