A novel way of uniform amplitude generation for calibration and testing of high-resolution nuclear spectroscopy systems

This paper presents a new method of uniform amplitude generation for calibration and testing of high-resolution nuclear spectroscopy systems using a new method of DAC interpolation. The uniform amplitude generator (UAG) is designed to generate pulses whose amplitude can be controlled in steps of 10 μV in the range of 0 to 10V. The designed circuit is simulated using Multisim v14.0 software. It is suitable to calibrate the spectroscopy systems with the resolution of as high as 13-bit. The uniform amplitude generator (UAG) is also modified using a sliding technique which slides the pulses in steps of 1 μV to make it capable for testing spectroscopy systems with resolution of up to 16-bit.
