Abstract:

This paper addresses the analysis and design of an upconversion mixer suitable for a multi-band analog interface for CMOS SOCs. This block must relocate an input signal from 3 different frequency bands (FM, VHF/UHF and CDMA/GSM) to a fixed IF frequency of 1.4 GHz. The mixer architecture is based on a Gilbert Cell and multi-tanh linearization technique, providing the required gain and linearity for different input frequencies. The mixer was designed in 0.18 μm CMOS process using the gm/ID design method. A 5bB gain, 12dB noise figure, and 1.5dBm IIP3 were obtained under different input frequencies.
