A multistandard, multiband SoC with integrated BT, FM, WLAN radios and integrated power amplifier

The growing occurrences of WLAN, BT, and FM on the same mobile device have created a demand for putting all three on the same die to save on die size, I/O count, BOM, and ultimately cost. Common blocks such as crystal oscillator, bandgap, and power management units can be easily shared. This paper presents a solution in which 802.11a/b/g WLAN, single-stream 11n (SSN) WLAN, BT, and FM subsystem and radio are integrated on a single die.

A dual mode 802.11b/Bluetooth radio in 0.35/spl mu/m CMOS

A dual-mode CMOS 2.4GHz transceiver consumes 65mA in RX and 78mA in TX from a 3V supply. The receiver achieves a typical sensitivity of -88dBm at 11Mb/s for 802.11b, and -83dBm for Bluetooth mode. The receiver minimum IIP3 is -8dBm, and the transmitter delivers a nominal output power of 0dBm, with a power control range of 20dB in 2dB steps.

A Single-Chip Bluetooth EDR Device in 0.13μm CMOS

A low-power single-chip Bluetooth EDR device is realized using a configurable transformer-based RF front-end, a low-IF receiver and direct-conversion transmitter architecture. It is implemented in a 0.13mum CMOS process and occupies 11.8mm2. Sensitivity for 1, 2 and 3Mb/s rates is -88, -90, and -84dBm and transmitter differential EVM is 5.5% rms.

An IF FSK demodulator for Bluetooth in 0.35 /spl mu/m CMOS

An FSK demodulator intended for use in Bluetooth is implemented in a 0.35 /spl mu/m CMOS process. The entire demodulator, integrated as a part of a low-IF receiver with 2 MHz intermediate frequency, consumes 3 mA from 2.7 V supply. The required signal-to-noise ratio (SNR) for 0.1% bit error rate (BER) is about 18 dB.

A fully integrated transceiver for Bluetooth

Bluetooth is a communication protocol enabling low-cost, short-range radio links between mobile phones, mobile PCs, and other portable devices. The Bluetooth standard specifies a 2.4 GHz; frequency-hopped, spread-spectrum system that supports a data rate of 1 Mb/s. This paper describes a low-cost, low-power, and highly integrated solution for 2.4 GHz short-range radio applications, such as Bluetooth.

A fully integrated SoC for 802.11b in 0.18 /spl mu/m CMOS

A fully integrated system-on-a-chip (SOC) intended for use in 802.11b applications is built in 0.18-/spl mu/m CMOS. All of the radio building blocks including the power amplifier (PA), the phase-locked loop (PLL) filter, and the antenna switch, as well as the complete baseband physical layer and the medium access control (MAC) sections, have been integrated into a single chip. The radio tuned to 2.4 GHz dissipates 165 mW in the receive mode and 360 mW in the transmit mode from a 1.8-V supply. The receiver achieves a typical noise figure of 6 dB and -88-dBm sensitivity at 11 Mb/s rate. The transmitter delivers a nominal output power of 13 dBm at the antenna. The transmitter 1-dB compression point is 18 dBm and has over 20 dB of gain range.

A 2.4 GHz CMOS transceiver for Bluetooth

A fully-integrated CMOS transceiver tuned to 2.4 GHz consumes 46 mA in receive mode and 47 mA in transmit mode from a 2.7 V supply. The receiver has -80 dBm sensitivity at 0.1% BER, and -7 dBm IIP3. The transmitter delivers a GFSK modulated spectrum at 5 dBm output power.
