A laser-detector-hologram unit with IV amplifiers and built-in micro-mirror

This LDH unit integrated with five bipolar amplifiers and a built-in micro-mirror realizes read-out characteristics corresponding to quad-speed (4x) of a CD-ROM drive. The fact that the output impedance of each IV amplifier is low, results in drastic reduction of stray noise. Simulating the response characteristics of the IV amplifiers determines the most suitable conditions for the LDH unit operating at 4x read-out speed of CD-ROM drive.
