Abstract(in English) | A low power highly linear CMOS RF amplifier circuit composed of Multiple Gated common-source FET TRansistor (MGTR) in cascode configuration is reported. In MGTR amplifier, linearity is improved by using transconductance linearization which can be achieved with canceling the negative peak value of g_m'' of the main transistor with the positive one in auxiliary transistor having different size and gate drive combined in parallel. This enhancement, however, is limited by the distortion originated from the combined influence of g_m' and harmonic feedback, which can greatly be reduced by cascoding MGTR output. IP3 improvement as large as 10dB has been obtained from an experimental RF amplifier designed at 900 MHz and fabricated using 0.35μm BiCMOS technology using only CMOS at similar power consumption and gain as those obtainable from conventional cascode single gate transistor amplifier. |
