A 3.3-V, 1.9-GHz, high linear CMOS up-mixer with multi-tanh linearization technique
2005
This paper presents a single side band up-mixer implemented in SMIC 0.35 mum CMOS technology. It can be used in low-IF direct conversion PCS 1900 (1850-1910MHz) transceiver systems. The mixer is based on multi-tanh linearization technique and achieves high linearity. It operates at a single power supply of 3.3V and consumes only 6mA. The up-mixer with the output buffer achieves an IIP3 of 8dBm and a 1-dB compression point of 0dBm
