A 43mW Bluetooth transceiver with -91dBm sensitivity

A Bluetooth transceiver has -91dBm sensitivity while drawing 24mA from a 1.8V supply. The receiver has a low-IF path with 30dB image and 9dB co-channel rejection, 80dB of AGC, digital equalization and complex PLL demodulation. The transmitter uses direct two-point modulation and draws 18mA at +6dBm...

Description
Summary:A Bluetooth transceiver has -91dBm sensitivity while drawing 24mA from a 1.8V supply. The receiver has a low-IF path with 30dB image and 9dB co-channel rejection, 80dB of AGC, digital equalization and complex PLL demodulation. The transmitter uses direct two-point modulation and draws 18mA at +6dBm output power. The DS PLL settles in 100/spl mu/s. LDO regulators power the analog and digital sections.
