초록/요약
A low power CMOS pulse generator based on spectral efficiently gated oscillator for UWB multiband impulse radio is reported. The pulse generator is based on an on/off switched LC oscillator with the trapezoid switching pulse. By using trapezoid pulse for on/off switching signal of the oscillator, better output spectral characteristic can be achieved without additional pulse shaping filter due to the more symmetric triangular envelope of the output pulse. Output pulse spectrum shows more than 27 dB of sideband rejection without additional filtering. The pulse generator dissipates only 35 pJ per pulse from 1.2-V supply.
