Abstract:

This work presents a 5T2C pixel circuit for active-matrix (AM) micro-displays in near-eye display applications. The circuit supports monochrome micro light-emitting diode (micro-LED) displays with ultrahigh resolution of 7056 pixels per inch (PPI). The circuit is designed and fabricated based on medium-voltage (MV) devices from the 55-nm high-voltage (HV) CMOS …

Abstract:

The general approach to suppress leakage in static random access memory (SRAM) is to use a low voltage ( $V_{text {L}}$ ), generated by a low-dropout regulator (LDO), as the cell supply voltage (CVDD) of SRAM array in the standby mode. However, the effectiveness of lowering CVDD is constrained by the …
