DESIGN AND SIMULATE PULSE GENERATOR CIRCUIT

The main purpose of the project is to design and simulate pulse generator impulse
based for Ultra Wide Band (UWB) applications. The UWB technology is defmed by the
Federal Communications Commission's (FCC), the signal must have bandwidth of
greater than SOOMHz. The structure of the pulse generator is based on Complementary
Metal Oxide Semiconductor (CMOS) and the topology of the circuit is adaptation of CR(
RC)" pulse shaping network. The pulse generator circuit consists of variable length
rectangle pulse generator, which mingles up cascaded inverter and N-voltage controlled
with a CMOS quasi-Gaussian pulse-shaping filter. In this project, the author successfully
designed and simulated the pulse generator. The simulation is done using Virtuoso
Analog Design Environment (Cadence) which is able for integrated design circuit and
used AMI 0.6um transistor technology. The circuit takes lOOMHz pulse as the input.
Through the simulation, the author has proved to generate pulse with 660MHz passed
frequency. This shows that the topology chosen is able to generate pulse for high
frequency purposes.
