The present disclosure relates to a method and apparatus for determining a signal margin (SM) of a memory cell, a storage medium and an electronic device, and relates to the technical field of integrated circuits. The method for determining an SM of a memory cell includes: when the memory cell performs write and read operations, determining a sense signal threshold of the memory cell under an influence of a noise; and determining, based on the sense signal threshold, an actual SM of the memory cell during data reading.

Method and apparatus for determining signal margin of memory cell and storage medium

Disclosed are a method and apparatus for determining mismatch of a sense amplifier, a storage medium, and an electronic equipment, relating to the field of integrated circuit technology. The method for determining mismatch of a sense amplifier includes: determining a first signal threshold on a first bit line when a first memory cell executes write and read operations; determining a second signal threshold on a second bit line when a second memory cell executes write and read operations; and determining, according to the first signal threshold and the second signal threshold, whether the sense amplifier is mismatched. A method for determining whether the sense amplifier is mismatched is provided.

A broadband solar cell antenna includes a first solar cell layer, a first dielectric supporting layer, an antenna layer, a second dielectric supporting layer, and a second solar cell layer sequentially from top to bottom. The first and second solar cell layers are structurally identical; the first and second dielectric supporting layers are structurally identical; a monopole is a metal base copper-clad laminate in a shovel-shaped structure; a trumpet-shaped grounded coplanar waveguide (GCPW) feeding line is used; and a solar cell array forms a meta-surface structure. The broadband solar cell antenna has the features of broadband, miniaturization and low profile. The antenna layer is provided between the two solar cell layers. Solar cells on an upper surface and a back surface of the antenna can collect light in different angles. The antenna has desired radiation performance and can function as both an antenna and a solar cell.
