The paper presents the design and simulation of a 5GHz monolithic low-noise amplifier integrated with an active Balun. Intended to WLAN applications, the fully integrated circuit was implemented in a 0.18um CMOS technology. The simulations, optimized to noise performance, gain and minimum differential phase and magnitude error, were performed with BSIM3 model. Circuit simulations present 23dB differential power gain at 5GHz, a phase and a transducer gain magnitude errors less than 1º and 0.2dB, respectively, in a 100MHz span around 5GHz, NF =3.6dB, 1dBCP = -22dBm, IIP3 = -8dBm, 50ohm input and output match, while drawing 8mA from a 1.8V power supply.
