  • Publication number: 20220300694
    Abstract: A phase shifter includes a first transistor and a second transistor. The first transistor includes a first gate terminal configured to receive a first voltage. The first transistor is configured to adjust at least a resistance or a first capacitance of the phase shifter responsive to the first voltage. The second transistor is coupled to the first transistor. The second transistor includes a second gate terminal configured to receive a second voltage. The second transistor is configured to adjust a second capacitance of the phase shifter responsive to the second voltage. The second gate terminal includes a first polysilicon portion and a second polysilicon portion extending in a first direction. The first polysilicon portion and the second polysilicon portion are positioned along opposite edges of an active region of the first transistor and the second transistor.

  • Patent number: 11393937
    Abstract: The present disclosure relates to an integrated chip that has a light sensing element arranged within a substrate. An absorption enhancement structure is arranged along a back-side of the substrate, and an interconnect structure is arranged along a front-side of the substrate. A reflection structure includes a dielectric structure and a plurality of semiconductor pillars that matingly engage the dielectric structure. The dielectric structure and semiconductor pillars are arranged along the front-side of the substrate and are spaced between the light sensing element and the interconnect structure. The plurality of semiconductor pillars and the dielectric structure are collectively configured to reflect incident light that has passed through the absorption enhancement structure and through the light sensing element back towards the light sensing element before the incident light strikes the interconnect structure.

  • Patent number: 10915963
    Abstract: An investment strategy rule generation method including the following steps is provided. Firstly, an investment strategy rule generator generates an investment strategy model according to an investment history trend. Then, a total investment return of each of N candidate investment rules is obtained by the investment strategy rule calculator, wherein each of the N candidate investment rules includes a candidate market direction rule. The obtaining step includes: performing an investment simulation in each of multiple time points in a time window of a time interval. Then, the total investment return under the operation of the investment simulations over the time interval is calculated by the investment strategy rule calculator. Then, the candidate investment rule corresponding to the best of the total investment returns is used as an investment strategy rule of the investment strategy model by the investment strategy rule calculator.
