This Paper presents a highly-applicable supply modulator (SM) for WCDMA envelope tracking power amplifier (ET PA) system. An on-chip highly-linear envelope detector is employed so that no extra envelope signal from baseband is needed. The proposed SM chip reduces the complexity of ET technique application. It can be directly employed in transmitters without using other programming or elements. It...
A low power 60-GHz on-off-keying (OOK) receiver has been implemented in a commercial 90 nm RF CMOS process. By employing a novel on-chip antenna together with architecture optimization, the receiver achieves a sensitivity of -47 dBm at a bit-error rate (BER) of less than 10-3. Using a commercial transmitter with transmit power of 1.5 dBm, a transmission distance of 5 cm can be achieved at 1.2 Gbps...
A low power 60-GHz on-off-keying (OOK) receiver is implemented in a commercial 90nm RF CMOS process. The receiver includes on-chip antenna, LNA, 60GHz detector and limiting amplifier, all implemented differentially. The receiver achieves BER of 4.7??10-6 for data rate of 1.2Gbps at a transmitting distance of 10cm and consumes power of 42 mW. Higher energy efficiency of 28pj/bit can be achieved at...
