A 4.6 μW, 133-VPP Common-Mode Interference-Tolerant Biopotential Amplifier for Two-Electrode Recording System in 110-nm CMOS 150 150

Abstract:

This article presents a biopotential recording analog front-end (AFE) specifically tailored for a two-electrode measurement system, capable of capturing small biopotential signals while tolerating a large common-mode interference (CMI) over 130 VPP. By leveraging the Miller effect, the proposed CMI-Follower provides a significantly low common-mode input impedance ( $Z_{\text {IN-CM-C}}$ ), achieving …

A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3

A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3 150 150

Abstract:

In this article, we propose a wideband mixer-first receiver with improved in-band (IB) linearity. It uses bootstrapped N-path mixer switches to achieve a constant on-state gate–source voltage for large IB signals. We analyze the tradeoff between on-state resistance and off-state subthreshold current in conventional mixer switches and introduce a …

A 28-nm 8–28-GHz Eight-Phase Clock Generator Using an Injection-Locked Dual-Feedback Ring Oscillator

A 28-nm 8–28-GHz Eight-Phase Clock Generator Using an Injection-Locked Dual-Feedback Ring Oscillator 150 150

Abstract:

The injection-locked ring oscillator is being widely used in high-speed wireline transceivers to generate multi-phase clocks. The fundamental limit lies in the tradeoff between the number of output phases and the maximum operation frequency for a given technology node. This work proposes the dual-feedback ring oscillator that breaks the tradeoff …

Ultra-Low-Power Dynamic-Bias Comparators With Self-Clocked Latch in 65-nm CMOS

Ultra-Low-Power Dynamic-Bias Comparators With Self-Clocked Latch in 65-nm CMOS 150 150

Abstract:

This article introduces two comparators featuring a dynamic-bias preamplifier and self-clocked latches, tailored for ultra-low-power and medium-speed applications with <500- $\mu $ V input-referred noise (IRN). The proposed self-clocked latches are activated by the preamplifier outputs and therefore operate with a lower common-mode current, which in turn minimizes the crowbar current …

DPIM: A 2T1C eDRAM Transformer-in-Memory Chip With Sparsity-Aware Quantization and Heterogeneous Dense–Sparse Core

DPIM: A 2T1C eDRAM Transformer-in-Memory Chip With Sparsity-Aware Quantization and Heterogeneous Dense–Sparse Core 150 150

Abstract:

Transformer models have revolutionized artificial intelligence (AI) applications across various domains, but their increasing complexity poses significant challenges in terms of computational and memory demands. While processing-in-memory (PIM) paradigms have been adopted to address these limitations, existing PIM-based transformer accelerators still face hurdles such as: 1) focusing solely on optimizing attention …
