Abstract

A 94 GHz mm-Wave LNA targeted for imaging system is designed and fabricated in 55 nm CMOS process. The dual-coupling g_m-boosting technique is proposed to achieve high gain and wide-band input matching. Meanwhile, in order to improve the gain and ensure the stability of the proposed LNA, the capacitance neutralization method and the common-gate-shorting technique are simultaneously introduced. The measurement results indicate that the LNA achieves a small signal gain of 14.2 dB, a BW-_3dB of 87.1~95 GHz, a NF of 6.7dB as well as an input-referred 1 dB compression point of -13 dBm.
