摘要：

A 4-GHz 1.2-V all-analog wireless reflector acting as a cooperative diversity repeater is built in 0.13-mu m CMOS technology. Interfaced with a dipole antenna, the circuit achieves 22.3-dB gain for a low power consumption equal to 120 mu W. By applying slow phase sweeping at the reflector node, diversity gain is achieved and the coverage area of an indoor wireless network is increased by a factor of 2.5.
