We present a rapid on/off transmitter using a two-stage cascaded clock multiplier that generates a 2.46-4.92GHz clock from 38. 4MHz clock, and a voltage-mode output driver with fast-on regulators for ...

This paper presents an RFDAC transmitter for impulse-radio ultra-wideband (IR-UWB) ranging and radar applications. The design takes 7-bit 2GS/s input data for modulating an RF carrier having a ...
