چکیده
This 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 0.18μm 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, 50Ω input and output match, while drawing 8mA from a 1.8V power supply.

A-1.8V Operation Switchable Direct-Conversion Receiver with sub-harmonic mixer
This paper reports on a fully-integrated CMOS switchable directconversion receiver for 2GHz and 5GHz. Switchable low noise amplifier is proposed for suiting for multiband (2GHz, 5GHz). Sub-harmonic mixing is used for down-conversion to minimize the DC-offset due to LO-leakage. The residual DC-offset is cancelled by a digital-to-analog converter at the output of mixer. For quadrature down-conver...
