A single-chip 33pJ/pulse 5th-derivative Gaussian based IR-UWB transmitter in 0.13µm CMOS

A low-power full 3.1–10.6GHz UWB transmitter using very simple 4-delay-cell 5th-derivative Gaussian pulse generation for carrier-free IR-UWB system is designed and fabricated in 0.13µm CMOS. The fully integrated IR-UWB transmitter features on-chip compensated active balun and simple BPSK modulation. Measurement shows the lowest reported power of 33pJ/pulse at 100MHz PRF, short 5th-derivative Gaussian pulse width of 750ps and Vpp of 84mV. This FCC-compliant IR-UWB transmitter allows up to 1.3Gbps throughput for low-cost low-power hi-QoS wireless multimedia and video streaming.
