Correction: Jegannathan et al. An Overview of CMOS Photodetectors Utilizing Current-Assistance for Swift and Efficient Photo-Carrier Detection. Sensors 2021, 21, 4576

There was an error in the original publication, in Equation (5). The sign × needs to be changed to ∗ (the sign for convolution). In Section 3.2, Equation (5) appears as:

$$\mathrm{s}\left(\mathrm{t}\right)=\left[\mathrm{o}\left(\mathrm{t}\right){\times \mathrm{rect}}_{\mathrm{CAPD}}\left(\frac{\mathrm{t}}{{\mathrm{t}}_{\mathrm{pd}}}\right)\right]\times \sum _{\mathrm{n}=-\infty }^{+\infty }\mathsf{\delta }\left(\mathrm{t}-\frac{\mathrm{n}{\mathrm{T}}_{\mathrm{mod}}}{\mathrm{m}}\right)$$

(5)

and it should be changed to:

$$\mathrm{s}\left(\mathrm{t}\right)=\left[\mathrm{o}\left(\mathrm{t}\right){\ast \mathrm{rect}}_{\mathrm{CAPD}}\left(\frac{\mathrm{t}}{{\mathrm{t}}_{\mathrm{pd}}}\right)\right]\times \sum _{\mathrm{n}=-\infty }^{+\infty }\mathsf{\delta }\left(\mathrm{t}-\frac{\mathrm{n}{\mathrm{T}}_{\mathrm{mod}}}{\mathrm{m}}\right)$$

The original publication has also been updated [1].
