Abstract:
A novel preamplifier system to improve the performance of zero-crossover optical encoders is presented. The network is based on a low-noise operational amplifier with a Zener diode feedback. We propose to exploit the non-linear characteristic of this network to reduce the angular measurement uncertainty. The circuit has been accordingly developed and tested in operation.
