This work presents a methodology for designing CMOS low-voltage low-power low-noise amplifiers (LNAs) based on the inductively degenerated common-source topology. To demonstrate the application of the proposed method, two LNAs operating at 900MHz and 2.4GHz are designed and simulated using a 90nm CMOS process. The 900MHz (2.4GHz) design has noise figure of less than 5.5dB (5dB) over the entire band of interest, a power gain of 12dB (13dB), input 1dB compression point of -20dBm (-18dBm), input-referred third-order intercept point of -10dBm (-9dBm), and consumes 1.6mW (2.8mW) from a 0.45V (0.5V) supply. Both LNAs are matched to 50Omega input and output impedances. The LNAs are designed for operation in the industrial, scientific, and medical (ISM) band and are intended for systems using the IEEE 802.15.4 (Zigbee) low-power standard
