A UHF mobile single chip RFID reader is implemented in 0.18 mum CMOS process. Developed IC achieves DA output power of 3 dBm, <i>OIP</i>3 of 14.8 dBm, phase noise of -100 dBc/Hz at 100 kHz offset, noise figure of 35.5 dB for talk mode, 6.2 dB for listen before talk (LBT) mode, and current consumption of 108 mA from a 1.8 V supply. With an external PA, Tx(More)
A wideband linearization technique using tunable multiple gated transistors (MGTRs) is proposed. Extra tunable input capacitors and the modified derivative superposition (DS) method are also adopted to increase the amplifier's linearity at RF. A low-noise amplifier (LNA) employing the proposed linearization technique has been developed with 0.18-&#x03BC;m(More)
