2V 0.2-to-6.3GHz transceiver for a multimode radio is fabricated in a 0.13µm CMOS technology. Figure 10.8.1 shows the measured matching characteristics of the transmitter (S22), receiver (S11) and EVM of the transmitted signal. The transmitter achieves EVM of less than −29.5dB at −3dBm output from 0.2 to 7.2GHz while consuming 69mW, where the modulation scheme used is equivalent to 802.11a, 54Mb/s mode. Without any explicit matching components, S22 and S11 are kept less than −9.5dB and −9.2dB, respectively, over the frequency range from 0.1 to 6.3GHz. To achieve wideband output matching, a parallel combination of a common-source amplifier and a source-follower buffer is used. This structure copes with both 50Ω output resistance, and small output capacitance. The choke in the pre-power-amplifier (PPA) is also
