Author(s): Saroj Satapathy, Amlan Ghosh, John Riley, Jalal Quadri, Jaydeep Kulkarni, Feroze Merchant

Abstract:

Advanced CMOS memory requires voltage biasing assist techniques to achieve low operating voltages (Vmin), which must be deactivated at higher voltages for high electric field reliability. Centralized Power Management Unit (PMU) control signals face timing synchronization and process tracking challenges when distributed across cores to activate assist circuits in various …

SHINSAI: A 586 mm2 Reusable Active TSV Interposer With Programmable Interconnect Fabric and 512 Mb Underdeck Memory 150 150
Author(s): Haozhe Zhu, Bo Jiao, Yuman Zeng, Yongjiang Li, Jie Liao, Siyao Jia, Zexing Chen, Liyu Lin, Xuanda Lin, Suchang Huang, Mochen Tian, Jundong Zhu, Dexin Wen, Yan Wang, Yu Wang, Jian Xu, Feng Wang, Jun Tao, Chixiao Chen, Qi Liu, Ming Liu

Abstract:

This article presents SHINSAI—a 586 mm2 reusable active through-silicon via (TSV) interposer addressing key challenges in multi-chiplet integration (MCI) architectures. While active interposers overcome fundamental limitations of passive counterparts by integrating functional circuitry, existing solutions face three critical constraints: 1) non-recurring engineering (NRE) costs from application-specific interposers negating chiplet reuse benefits; 2) …

A 37.8 Mb/mm² SRAM in Intel 18A Technology Featuring a Resistive Supply-Line Write Scheme and Write-Assist With Parallel Boost Injection

A 37.8 Mb/mm² SRAM in Intel 18A Technology Featuring a Resistive Supply-Line Write Scheme and Write-Assist With Parallel Boost Injection 150 150
Author(s): Harold Pilo, Manish Arora, Chien-An Lai, Mike Lee, Zack Lo, Mayur Randeria

Abstract:

A high-density (HD), SRAM-based register file (RF) has been demonstrated in Intel 18A Technology (Wang et al., 2025 and Pilo et al., 2025) featuring RibbonFET GAA transistors and a back side power delivery network (BSDPN). The RF is optimized for HD and array efficiency and achieves a density of 37.8 Mb/mm2, the …

Non-Volatile ReRAM-Based Compact Event-Triggered Counters

Non-Volatile ReRAM-Based Compact Event-Triggered Counters 150 150
Author(s): Moin Diwan, Shengchao Zhang, Zidu Li, Alex James, Bhaskar Choubey

Abstract:

With an increasing number of transistors per circuit, the fabrication cost and the energy consumption of each integrated circuits increase exponentially, which drives the need to reduce the number of transistors. In this study, we explore a novel design for a 16-bit digital counter that utilizes a combination of complementary …

An Area and Power Efficient Source Driver IC With Multi-Line Sensing Real-Time Pixel Compensation for OLED Displays

An Area and Power Efficient Source Driver IC With Multi-Line Sensing Real-Time Pixel Compensation for OLED Displays 150 150
Author(s): Jaewoong Ahn, Seung Hun Choi, Minseong Um, Jun Yeol An, Hyung-Min Lee

Abstract:

This article proposes a source driver integrated circuit (SD-IC) with a pixel compensator designed to minimize both silicon area and power consumption for organic light-emitting diode (OLED) displays. The proposed SD-IC is capable of driving ultrahigh-definition (UHD) active-matrix OLED (AMOLED) panels with a one-horizontal-time (1-H time) of $7.2~\mu $ s while …

A Low-Jitter Fractional-N Digital PLL Using a Quantization-Error-Compensating BBPD and an Orthogonal-Polynomial-Based LMS Calibration

A Low-Jitter Fractional-N Digital PLL Using a Quantization-Error-Compensating BBPD and an Orthogonal-Polynomial-Based LMS Calibration 150 150
Author(s): Munjae Chae, Seheon Jang, Seungjae Lee, Jaehyouk Choi

Abstract:

This work presents a 10.0–11.5-GHz fractional- $N$ digital phase-locked loop (DPLL) using the quantization-error-compensating bang–bang phase detector (QEC-BBPD) that can minimize both the static delay ( $T_{\mathrm {S}}$ ) and the dynamic delay ( $T_{\mathrm {D}}$ ) required for removing the delta-sigma modulator’s ( $\Delta \Sigma $ M) quantization-error (Q-error). Since the …
