Abstract
A CMOS LNA design and Gilbert double balanced mixer design for indoor wireless application are presented in this paper. The LNA is designed with current reused technology for lowering the dc power consumption, and the current-bleeding approach is adopted in mixer design for boosting its conversion gain, respectively. The Narrow band LNA achieves the gain of 20dB with noise figure of 1.5dB at 787MHz. The power consumption of LNA is 21.793μW. The proposed Gilbert double balanced mixer achieves the conversion gain of 13.365dB with Noise Figure of 2.12db and IIP3 as -2.8634dB for intermediate frequency of 100 KHz to 100MHz.
