An Ultra Low-Power FCC-Compliant 5th-Derivative Gaussian Pulse Generator forIR-UWB Transceiver

A FCC-compliant ultra low-power lowcost 5th-derivative Gaussian Pulse generator (PG) for full3.1-10.6GHz Impulse-radio (IR) carrier-free Ultra wideband (UWB) transceiver was designed and fabricated infoundry 0.131m CMOS. This PG integrates three cascadestages to generate square wave, Gaussian pulse and 5thorder Gaussian derivative waveform, respectively. Measurement shows the lowest reported power consumption of5.1pJ/pulse at 100MHz Pulse repeating frequency (PRF),the smallest die area of only 0.02mm2, short 5th-derivativeGaussian pulse width of 770ps and peak to peak amplitudeof 66mV. The FCC-compliant IR-UWB pulse generatorpotentially allows up to 1.3Gbps throughput for low-costlow-power hi-QoS wireless multimedia and video streaming.
