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
Author(s): Anojh Kumaran Rajendra, Harijot Singh Bindra, Bram Nauta

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 …

A Fully-Dynamic Capacitive Touch Sensor With Tri-level Energy Recycling and Compressive Sensing Technique

A Fully-Dynamic Capacitive Touch Sensor With Tri-level Energy Recycling and Compressive Sensing Technique 150 150
Author(s): Xiangdong Feng, Zhiyu Wang, Haoyang Li, Jiaqing Li, Wei-Chin Lin, Xin Hu, Zhong Tang, Yuyan Liu, Qinwen Fan, Yuxuan Luo, Bo Zhao

Abstract:

Capacitive touch screens have become the dominant user interface over the past decade. Achieving high framerates with low power consumption remains a critical design goal for touch systems. The conventional charge-recycling technique reduces driving power by 64%, but it relies on off-chip capacitors. To address this issue, we propose a tri-level …

A 430- μ A 68.2-dB-SNR 133-dBSPL-AOP CMOS-MEMS Digital Microphone Based on Electrostatic Force Feedback Control

A 430- μ A 68.2-dB-SNR 133-dBSPL-AOP CMOS-MEMS Digital Microphone Based on Electrostatic Force Feedback Control 150 150
Author(s): Jiaqi Dong, Qi Zhang, Xinwen Zhang, Yekan Chen, Yili Shen, Bo Zhao, Yuxuan Luo

Abstract:

This article introduces a high-acoustic-dynamic-range and low-power digital microphone based on the electrostatic force feedback control (EFFC). The proposed design adjusts the sensitivity of the micro-electro-mechanical system (MEMS) by adaptively biasing it at different input amplitudes, thereby extending the dynamic range (DR). The proposed adaptive biasing technique allows the induced …
