摘要:	摘要： Summary This paper introduces an optimized receiver architecture using the current‐reuse technique to improve receiver sensitivity while minimizing power consumption. An ISM band wireless receiver with OOK modulation was implemented in the TSMC 0.18‐µm CMOS process. The receiver contains an RF front end, an LC‐tank based LO VCO, an IF amplifier and an OOK demodulator. In addition, the IF amplifier features a self‐mixing elimination mechanism which allows the BER to upgrade more than one order of magnitude. Measurement results show a sensitivity of −63 dBm given a BER of 10−3. Using the gain‐improving method, the sensitivity is improved by 4 dB (100‐kbps data rate). Including the bias circuit, overall power consumption is less than 383 μW under a 1.2‐V supply, providing an alternate solution for wireless radio applications.

Introduce a new gain‐improving method to effectively improve sensitivity in wireless receivers, where (1) a programmable control bias current in the PPCRU RF front end providing a maximum gain operation with acceptable power consumption is included and (2) a design for transconductance (gm) is optimized, thereby reaching the maximum gain‐improving value (k). 其他題名： Int.
