    Abstract
    This thesis consists of two parts. The first part is the research regarding a low power consumption wideband mixer. This work has realized two chips, the first chip is a sub-harmonic mixer fabricated in tsmcTM 0.18 µm CMOS process. This mixer uses a doubler to obtain even order harmonics to perform sub-harmonic mixing. Meanwhile, a source driven technique is adopted to enhance the conversion gain. The measurement results shows the performance as follow, a conversion gain of -8.9 dB, a P1dB of -10.8 dBm, an IIP2 of 13.9 dBm, an IIP3 of -1 dBm, a DSB noise figure of 12.72 dB at -1 dBm LO power. The bandwidth is 5-12 GHz. The DC power consumption is 6.5 mW. The chip size is 0.788×1.165 mm2.
    The second realized chip is fabricated in UMC 0.18 µm CMOS process. A Ruthroff-type single to differential balun is applied for the wideband input matching. The switched biasing technique is for DSB noise figure improvement. And the bulk injection can reduce the power consumption. The measurement results shows the performance as follow, a conversion gain of 7.7 dB, a P1dB of -18 dBm, an IIP2 of 7.7 dBm, an IIP3 of -9.9 dBm, a DSB noise figure of 10.87 dB at 5 dBm LO power. The bandwidth is 5.2-12 GHz. The DC power consumption is 0.37 mW. The chip size is 0.765×1.444 mm2.
    A multi-function circuit incorporated with a up-mixer and a power amplifier is realized in tsmcTM 0.18 µm CMOS process. A differential transmission-line transformer is utilized for wideband power match. The measurement results achieves a conversion gain of 20.97 dB, a Psat of 15.02 dBm, an OP1dB of 13.06 dBm, an IIP3 of 3.26 dBm, an OIP3 of 22.94 dBm, a drain efficiency of 10.3% at 11 dBm LO power. The bandwidth is 5-12 GHz. And the DC power consumption is 171.68 mW. The chip size is 0.962×1.572 mm2.
