A 10b Display Driver IC with a Pivoting Translinear-Loop DAC-in-Buffer Enabling $1\mu\mathrm{s}1-\mathrm{H}$ Scan Time and $1722\mu\mathrm{m}^{2}$ Per Channel

This paper presents a 10b display driver IC (DDI) for high-resolution OLEDs. It features a novel pivoting translinear-loop (PTL) DAC-in-buffer that overcomes the area, speed, and linearity trade-offs. A key enabler is a floating voltage-mirror (FVM) that decouples coarse/fine domains, allowing an area-efficient 5b+5b architecture via true-DC interpolation while maintaining high linearity. Fabricated in 180nm CMOS, the DDI achieves a fast 1-H scan time of 1μs and a compact 1722μm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>/channel.
