A Very Low Complexity IR-UWB Transmitter with BPSK Modulation for Balanced Antenna

A very low complexity impulse radio-ultrawideband (IR-UWB) transmitter suitable for balanced antenna is presented. This all-digital transmitter employs the binary phase-shift keying (BPSK) modulation scheme and eliminates the need for a balun. Also, a new Gaussian monocycle pulse generator is proposed which is used as impulse transmitted signal. The transmitter circuit was designed in 0.18-m complementary metal-oxide-semiconductor technology. The post-simulation results show that the core chip size was only 0.02 mm(2). The output amplitude pulse yielded 150 mV peak-to-peak under a supply voltage of 1.8 V. Simulation results show that the transmitter consumes 8.5 pJ/pulse for 200-MHz pulse repeating frequency.
