| Abstract: | A kind of pulse peak holding circuit was designed to fulfill the technical demands of conventional A/D sampling circuit to capture peak voltage in the reception signal processing system of laser spot trackers. Firstly, several technical specifications of the holding circuit were analyzed theoretically and the MAX436, a high-speed and wideband trans-conductance amplifier, was effectively chosen to lay out the circuit. Following, the simulation analysis and experimental research were done to get experimental results that could meet the technical demands. For the laser pulse signal of 50ns pulse-width, the response speed of the peak holding circuit≤2 ns, the relative error≤1.1% and the droop speed rate≤6.0 mV/μs, when the amplitude of input signal≥100 mV. |
