CMOS Direct-Conversion RF Front-End Design for 5-GHz WLAN

A 5-GHz Direct-Conversion CMOS Transceiver

A CMOS transceiver fully compliant with IEEE 802.11a in the unlicensed national information infrastructure (UNII) band (5.15–5.35 GHz) achieves a receiver sensitivity of 5 dBm for 64-QAM (quadrature amplitude modulation) with an error vector magnitude (EVM) of 29.3 dB. A single-sideband mixing technique for local-oscillator signal generation avoids frequency pulling. Realized in 0.18m CMOS and ...

Current-mode design techniques in low-voltage 24-GHz RF CMOS receiver front-end

A new high frequency CMOS current-mode receiver front-end composed of a current-mode low noise amplifier (LNA) and a current-mode down-conversion mixer has been proposed in the frequency band of 24 GHz and fabricated in 0.13-lm 1P8M CMOS technology. The measurement of the current-mode receiver front-end exhibits a conversion gain of 11.3 dB, a noise figure (NF) of 14.2 dB, the input-referred 1-...

WCDMA Direct Conversion Front End in 0.13um digital CMOS

This project presents a direct-conversion 3G front end in 0.13um digital CMOS for use with the 2.1 GHz WCDMA frequency band. These receivers, widely used in 3G mobile telephony, require low power consumption and cost effective integration with other systems while maintaining high linearity and sensitivity. This project includes the design of a differential LNA, a double-balanced mixer and an on...

A transformer-loaded receiver front end for 2.4 GHz WLAN in 0.13 m CMOS technology

A 2.4 GHz radio frequency receiver front end with an on-chip transformer compliant with IEEE 802.11b/g standards is presented. Based on zero-IF receiver architecture, the front end comprises a variable gain common-source low noise amplifier with an on-chip transformer as its load and a high linear quadrature folded Gilbert mixer. As the load of the LNA, the on-chip transformer is optimized for ...
