To achieve ultimately flexible multi-core radio operation, wide-band receiver RF front-ends must be robust against interference well in excess of the requirements usually specified by a radio standard. In this paper, a highly selective, very linear low-noise transconductance amplifier (LNTA) capable of large-signal handling for current-mode receiver (RX) front-ends is proposed and implemented in 65-nm CMOS. It is shown that by combining on-chip high-Q bandpass filters with a push/pull class-ABdoi:10.1109/rfic.2013.6569556 fatcat:3jv5af2hrrfhnhlo4luzb6w56a
