This paper reviews and discusses the design of a low-power single-full-band (3.1-10.6 GHz) non- carrier impulse-radio ultra wideband (UWB) transmitter featuring 5th-order Gaussian derivative pulse shaping, integrated BPSK modulation, and 2.5 kV whole-chip ESD (electrostatic discharge) protection. The UWB transmitter design has been implemented in a commercial 0.18 μm CMOS technology with a very small die size of 0.25 mm2. The fabricated chips have demonstrated full functionality, extremely low power consumption of 0.14 pJ/p-mV, and an ultra short pulse width of 394 ps. This ESD-protected UWB transmitter has the potential to support wireless streaming to gigabit per second (Gbps).
