Abstract: A novel beamforming ultra-wideband (UWB) transmitter architecture capable of providing very fine angular resolution for imaging applications in the frequency range of 3-5GHz has been developed. This architecture utilizes a novel digital delay calibration technique to generate baseband signals with precise delay difference. The UWB pulse is generated from these signals with the help of all-digital UWB transmitters. The whole transmitter architecture is implemented in 0.13µm CMOS process. It provides a delay resolution of less than 10ps and consumes about 35.4mW of power from a 1.2V supply. The all-digital UWB transmitter implemented in the design provides the flexibility to shape the output UWB pulse and consumes 80pJ/pulse.
