The Internet of Things (IoT) is the third technological revolution in the information technology industry. The application of IoT products will help construct smart cities. Communication chips are the basis for the realization of the IoT. This article focuses on the design of a low noise amplifier (LNA) for the IoT in smart cities. The LNA combines a resistance feedback common source structure and noise cancellation technology to obtain input matching and low noise figure. The proposed LNA is fabricated in 0.18$\mu$m CMOS process, which can drive an external 50$\Omega$ load and achieve minimum NF of 2dB at 200M$\sim $930MHz and input return loss (S 11 ) better than -15dB, the achieved gain (S 21 ) and IPldB is 18.2 dB and -18.7dBm.
