Dynamic Compensation Technique for POF Curvature Sensors

Journal of Lightwave Technology, 2018
Polymer optical fibers (POF) can be applied as curvature sensors due to its high strain limits, fracture toughness, and flexibility in bend. However, POFs present viscoelastic behavior, which leads to a phase lag between the stress and strain. The polymer viscoelasticity can be associated to the high hysteresis and the errors that curvature sensors ...

A curvature-compensated bandgap reference with high PSR

2008 IEEE International Conference on Granular Computing, 2008
In this paper, a curvature-compensated current mode bandgap reference with high supply rejection(PSR) is presented, which is in a 0.5 um 2P2M n-well mixed signal CMOS technology. Several resistors are added to improve temperature coefficient(TC). Otherwise the supply noise is directly fed into the feedback loop of the bandgap circuit by utilizing a ...

A twice curvature compensated voltage reference with double frequency compensation

Microelectronics Journal, 2020
Abstract This paper presents a voltage reference (VR) with low temperature coefficient (TC) and full frequency high power supply rejection ratio (PSRR), the VR is fabricated by 0.18 μm CMOS process. The proposed VR uses different methods to compensate for the temperature curvature of the output voltage twice.

Compensators of Petzval field curvature and astigmatism

Journal of Optical Technology, 2021
Optical schemes of aplanatic and afocal compensators of field curvature and astigmatism are considered. A method of their design is proposed and application guidelines are presented. An example of designing a double-lens objective with an extended field and one compensator is presented.
