An inductorless high dynamic range 0.3 − 2.6 GHz receiver CMOS front-end

This paper presents a wideband receiver front-end implemented in 0.13 mum CMOS technology. The front-end consists of a low-noise amplifier (LNA), a quadrature mixer, and a frequency divider. Multi-gated transistors have been used to enable linearity tuning. The circuit employs no inductors and operates from 0.3-2.6 GHz with a tunable baseband bandwidth. The front-end achieves conversion voltage gain of 38 dB, 3.6 dB DSB NF, nominal -6.5 dBm IIP
₃
and +4 dBm when tuned in the high-gain mode. The chip consumes 35 mA from a 1.5 V supply.
