| dc.description.abstract | The proposed transmitter chip is fabricated in a standard 0.25um single-poly-five-metal CMOS process with low resistance substrate. It consists of a quadrature modulator, a quadrature VCO, and a power amplifier. This transmitter IC consumes only 45 mA from a 2.5V power supply voltage. With highly linear quadrature modulator and low phase-error quadrature VCO structure, the measured LO leakage, image rejection, second-order inter-modulation and third-order inter-modulation of the modulated signal at the output of transmitter achieve -59dBc, -57dBc, -60dBc, and -56dBc, respectively. The three-stage power amplifier is also integrated to provide a 9.8dBm output power with 15% efficiency for short-range wireless communication applications. | en_US |
