Design of RSSI for use of AGC in Multi-Standard RF system

This paper presents received signal strength indicator(RSSI) for use of automatic gain control in multi-standard RF system. In oder to compensate offset and input dynamic range in each RF input specification, we proposed RSSI with the function of the output control. The proposed RSSI have -95 ㏈m input sensitivity, 60 ㏈ input dynamic range control in 0.8V~1.2V control signal, and 62.34㎽ power dissipation with 3.3V power supply and it was simulated by using 0.35㎛ CMOS process library.
