Paper Abstract

An integrated CMOS RF front-end receiver complying with the DECT standard is presented. It is implemented in a standard 0.35μm CMOS technology operating with 2 V power supply and includes the Low Noise amplifier (LNA), the quadrature mixer and the frequency synthesizer. The frequency synthesizer is based on an integer-N Phase Locked Loop (PLL) and uses two coupled Voltage Controlled Oscillators (VCOs) for direct I/Q generation. The packaged circuit exhibits 9.2dB NF, -19.5 dBm IIP3, 27.5 dB gain and consumes 30mA. This work demonstrates the feasibility of an integrated RF front-end for a wide band standard using a direct conversion architecture that minimizes the number of external components and a cheap standard CMOS technology.
