Abstract:
1. A system, comprising: a sequence control stage including a pulse enable input node and a plurality of output branches, wherein the sequence control stage is operative, in response to receiving a pulse enable signal at the pulse enable input node, to provide signals at the plurality of output branches at a plurality of time offsets; a pulse generation stage including at least two pulse generators, wherein each pulse generator has an input node coupled to a respective output branch of the sequence control stage, and wherein each pulse generator is operative to generate at an output node a Gaussian-like pulse in response to a signal from the respective output branch of the sequence control stage; and an output stage comprising a plurality of transistors and coupled to the output nodes of the Gaussian-like pulse generators and operative to combine the Gaussian-like pulses into an ultra-wideband pulse, wherein the ultra-wideband pulse approximates an Nth derivative of a Gaussian distribution, where N>0.
