A CMOS Ultra-wideband radar transmitter with pulsed oscillator
A design of Ultra-wideband (UWB) radar transmitter is presented. The transmitter which uses a pulsed oscillator consists of pulse generator, switching buffers and control signal generator. The control signal generator includes modulators of binary-phase shift keying (BPSK) and pulse position modulation (PPM) for spreading the spectral lines. It is fabricated using 0.13 µm CMOS technology and the chip size is 910 × 485 µm2. The output spectrum is centered at the 22.0 GHz with the 10-dB bandwidth of 2.48 GHz and the pulse width of output pulse is tunable from 630ps to 830ps. Also, the BPSK and PPM modulations are confirmed. In conclusion, the generated pulse complies with FCC's spectral mask.
