This paper presents a V-band low-noise amplifier with high RF performance and ESD robustness. An inductor-triggered silicon-controlled rectifier (SCR) assisted with both a PMOS and an inductor is proposed to enhance the ESD robustness and minimize the impact of the ESD protection block on the millimeter-wave LNA. The initial-on PMOS improves the turn-on speed and the inductor resonates with the parasitic capacitance, respectively. Also, a 3-stage wideband V-band LNA is designed by using the gate inductor in the common-gate stage of the cascode topology as gain peaking to compensate the roll-off at high frequencies for bandwidth extension. The measured results demonstrate a 2.5-kV HBM ESD protection level with a minimum noise figure (NF) of 5.1 dB and a peak gain of 22 dB, also a 3-dB bandwidth of 56-67 GHz can be achieved under a power consumption of only 23 mW.
