A fully-integrated 900-MHz CMOS wireless receiver with on-chip RF and IF filters and 79-dB image rejection

A truly-monolithic 900-MHz CMOS wireless receiver with on-chip RF and IF filters and a fully-integrated fractional-N synthesizer is presented. Implemented in standard 0.5-μm CMOS process and without any off-chip component, the receiver measures an image rejection of 79dB, sensitivity of -90dBm, IIP3 of -24dBm and NF of 22dB with power of 227mW and a chip area of 5.7mm². The synthesizer achieves a phase noise of -118dBc/Hz at 600kHz offset and settling time of less than 150μs
