Abstract

We have developed maximum and minimum voltage sample and hold circuits employing operational amplifiers (OPAMPs) composed of polycrystalline silicon (poly-Si) thin-film transistors (TFTs). It was confirmed that the maximum and minimum voltages are successfully sampled and held. It was also confirmed that the restoring ratio has a peak near a certain value of the operation frequency. We would like you to propose novel applications using these circuits.
