A 2.4-GHz direct-conversion RF front-end designed in a 65-nm CMOS process is described in this paper. The front-end includes an LNA, folded quadrature mixers, a local oscillator (LO) divider, and LO buffers. The front-end consumes 29.3 mA from a 1.2-V power supply and according to simulations it achieves 39-dB voltage gain, 1.5-dB minimum spot noise figure, and -17-dBm IIP3.
