Background: This paper presents a novel Ultra-Wideband (UWB) balanced sub-nanosecond
monocycle pulse generator sing Step Recovery Diodes (SRD) for an inter/intra-chip wireless
interconnect communication system.
Methods: The new UWB monocycle pulse generator has been simulated using Advanced Design
System (ADS). This pulse generator employs wideband microwave bipolar transistor, transmission line,
Schottky diodes and compact charging and discharging circuitry. Simple transient analysis and design
of the circuit are presented along with their operating principles. The pulse generator produces truly
balanced monocycle pulse having 200-ps pulsewidth, 2V peak voltage and 10-MHz repetition rate.
Results: The generated monocycle pulses also have very symmetrical positive and negative portions
and low ringing level.
Conclusion: It can be used as both transmitter feeding UWB balanced antennas without broadband
balun and UWB receiver balanced pulse generator that switches the sampling gate which commonly
consists of two or four Schottky diode.
