摘要：

A wideband inductorless LNTA is proposed in this paper. The active shunt feedback schematic ensures a wideband input matching while the noise cancellation configuration enables a small NF. The adopted current mirror load operating the LNTA in current mode alleviates the NF deterioration under blocker interference and maintains acceptable linearity as well. Simulations in 0.18-mu m CMOS technology show that the proposed LNTA achieves a minimum NF of 2 dB, and a maximum transconductance of 92 mS from 0.1 to 2 GHz. A P-1dB of -7.5 dBm and an IIP3 of -0.6 dBm are obtained, respectively. The circuit draws only 4.5 mA from a 1.8 V supply.
