In the switching power supply system, an error amplifier has a hysteretic design at a later stage thereof, and outputs COMP, which is an amplified signal obtained from a sampling signal of VOUT and a reference voltage, such that an output signal feedback node FB has a reduced amount of operating hysteresis, thereby achieving small output signal ripples. Moreover, a triangular wave signal Ramp is generated by a triangular wave generation circuit, and undergoes a hysteretic comparison with the COMP output by the error amplifier. A slope of the triangular wave signal Ramp is basically unrelated to the voltage at a sampling commutation point SW, such that the operating frequency of the system is mostly unrelated to output current load. The system also has fast transient response speed, and the operating frequency thereof is less affected by system inputs and outputs.

Title: Multilayered optical security device
Inventor: BEN AZIZA ZEINEB
IPC: G03H1/02
Filed: 2020-07-28
Abstract: A multilayered optical security device (100) has a resonant waveguide grating (RWG) layer (110) on an under layer (120) having a hologram. The RWG layer (110) has plural RWGs (601-625) for generating one or more patterns. Each RWG (601-625) has the first and second RWG portions (301, 302), with diffraction gratings (320, 330) of different grating periods, for light coupling-in and coupling-out, respectively. Using the RWGs (601-625) minimizes interference to a holographic image generated by the under layer (120). This advantage is especially useful when the holographic image carries digital data such as in digital holographic encryption where an encrypted hologram is used in the under layer (120). The digital data may contain biometric information such as a fingerprint. In each RWG portion (301, 302) of an individual RWG (601-625), scattering elements (321, 331) in a grating (320, 330) are curved to thereby enhance an angular tolerance in azimuthal angle during observing the patterns by an observer while the individual RWG (601-625) is still selective in elevation angle.
