Reduced Power Laer Designation Systems

Abstract

This work contributes to the Micropulse Laser Designation (MPLD) project. The objective of MPLD is to develop a 6-lb eye-safe micro-pulse laser system to locate, identify, range, mark, and designate stationary and moving targets. MPLD presents a range of new circuit design and signal processing problems, and the present work seeks to address some of these problems. Work for month 2 has involved investigating the use of a negative impedance converter circuit to reduce the effect of the photodiode capacitance, investigating a two-transistor circuit for bootstrap buffering of the input stage, comparing the noise performance of the candidate amplifier designs, selecting the two-transistor bootstrap design as the circuit of choice, and comparing the performance of this circuit against that of a basic transconductance amplifier. Results of simulation indicate that the chosen circuit meets all design specifications.
