The modulation signal is generated by selecting one of the four quadrature phases to the TX output via a proposed Phase MUX. An inverter-type power amplifier is utilized for it is compatible with the quasi constant-envelope nature of the O-QPSK modulation. Fabricated in a 0.18-μm CMOS process, the whole TX draws 2.9 mA from a 1.2-V supply. With a maximum 15Mbps data rate, the TX achieves an energy efficiency of 0.23 nJ/bit and delivers an output power up to -7 dBm. © 2008 IEEE. |
