This paper presents some techniques to synthesize pulses in the context of IR-UWB. Pulse synthesizers are good candidates when different kinds of pulses are needed to comply with different standards or when the shape of the pulses needs to be modified. Two different approaches are described here. Voltage Controlled Delay Line (VCDL) based pulses are first described. For this family, two kinds of combiners...
This paper presents the design of a fully integrated ultra-wideband (UWB) pulse generator for the Federal Communications Commission (FCC) 3.1-10.6-GHz band. This generator is reserved for medium rate applications and achieves pulses for an on-off keying (OOK) modulation, pulse position modulation, or pulse interval modulation. This UWB transmitter is based on the impulse response filter method, which...
