Abstract: A piece-wise linear logarithmic amplifier is presented.It can be used as limiting amplifier and received-signal-strength indicator (RSSI) in Bluetooth receivers.The circuit, as a part of Bluetooth RF chip, is implemented with the 0.35 μm CMOS technology.Measurements show that RSSI linear error is less than 0. 5 dB with a dynamic range of 40 dB.

Key words: Bluetooth, low power, piece-wise linear logarithmic amplifier, limiting amplifier, received signal strength indicator
