| 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. |

| Keywords: | Bluetooth low power piece-wise linear logarithmic amplifier limiting amplifier received signal strength indicator |
