Abstract :
This paper describes the design and simulation of an innovative monolithic active balun integrated with low noise amplifier. The fully integrated circuit was implemented in a 0.35 mum AMS CMOS standard technology. The simulations, optimized to noise performance, minimum differential phase and magnitude error, were performed with BSIM3 model. The complete circuit presents 20.6 dB differential power gain at 2.4 GHz, a phase and a transducer gain magnitude errors less than 0.2deg and 0.04 dB, respectively, in a 1 GHz span around 2.4 GHz, a 3.7 dB noise figure, a 2 dBm output-referred ldB compression point, 50 Omega input and output match, while drawing 11 mA from a 3 V power supply.
