Terahertz detectors are a key component for terahertz imaging, where detector arrays are preferred over single-pixel detectors for reduced scan time and potential for real-time imaging. While a lager pixel count is often desired for arrays, there is a limit on the maximum number of pixels that can be included in a semiconductor chip array. In this work, to overcome the pixel count limit, multi-chip technique has been applied for 600-GHz CMOS detector arrays, in which adjacent chips are stitched with wire-bonds for control and detection signal transfer. Two types of detector arrays have been developed and their electrical characteristics as well as the acquired 600-GHz test images are presented.

Proposed is an 11‐bit source driver IC for high‐resolution OLED displays, utilizing a Double Capacitor Coupled Adder (DCCA) for parallel sampling and driving. A Slew Rate Enhancement (SRE) circuit ensures fast response under minimal voltage differences, while Offset Calibration minimizes inter‐channel voltage deviations. Experimental results show a 2.0 μs line time, 9.9 V/μs slew rate, and a DVO of 2.43 mV, showcasing precision and efficiency.

Cost‐effective Display Driver IC architecture with an external memory is presented. Low‐power and high‐speed memory interface is proposed to minimize the increase of power consumption and the number of pins. The measured power consumption was less than 45mW with four 1.6Gbps data lanes, 1 clock lane and 1 command lane.
