“…It should be noted that the mismatch parameters of M d1 are canceled when V gs from Equation ( 6) is substituted into Equation (5). As a result, when neglecting the channel-length modulation effect, the circuit can drive the emitter current regardless of the current-driving transistor mismatch.…”

“…An infrared scene projector (IRSP) is a widely used piece of equipment that projects infrared (IR) images to investigate the performance of IR sensors [1][2][3][4][5][6][7]. These projectors are composed of IR emitters and driver integrated circuits (ICs) that are called read-in integrated circuits (RIICs) and are responsible for driving current to the IR emitters.…”

In this study, a novel IR projector driver that can minimize nonuniformity in electric circuits, using a dual-current-programming structure, is proposed to generate high-quality infrared (IR) scenes for accurate sensor evaluation. Unlike the conventional current-mode structure, the proposed system reduces pixel-to-pixel nonuniformity by assigning two roles (data sampling and current driving) to a single transistor. A prototype of the proposed circuit was designed and fabricated using the SK-Hynix 0.18 µm CMOS process, and its performance was analyzed using post-layout simulation data. It was verified that nonuniformity, which is defined as the standard deviation divided by the mean radiance, could be reduced from 21% to less than 0.1%.
