Abstract :
Two different low power CMOS limiters with received signal strength indicators (RSSIs) are presented. RSSIs are implemented using piecewise linear logarithmic amplifiers. The limiters and RSSIs are designed for Bluetooth receivers at 3 MHz IF using 0.35 μm and 0.5 μm CMOS technologies. Input dynamic range of the limiters is more than 65 dB, and RSSI error is within ±3 dB which satisfies Bluetooth requirements. The limiters with RSSIs consumes 1.2 mA and 1.6 mA with 2.7 V power supply
