FeFET-Based CMOS Current Starvation Programmable Delay Element

FeFET-Based CMOS Current Starvation Programmable Delay Element 150 150
Author(s): Albi Mema, Simon Thomann, Hussam Amrouch

Abstract:

Programmable delay elements (PDEs) are crucial circuit building blocks that enable precise timing adjustments of signal transitions. They are used in various critical applications, like time-to-digital converters. They are often used to mitigate aging by clock skew tuning post-fabrication. However, typical CMOS PDE designs require many transistors while still offering …

A 760 mVPP-Input-Range, 103.6dB-SNDR Direct-Digitization Sensor Readout With Pseudo-Differential Integrator and Impedance-Equalized RDAC 150 150
Author(s): Kaiwen Zhou, Jianhong Zhou, Yijie Li, Yuying Li, Tian Dong, Zhiliang Hong, Jiawei Xu

Abstract:

A high-precision, direct-digitization sensor readout (DD-RO) based on a continuous-time delta-sigma modulator (CT- $\Delta \Sigma $ M) is presented. The proposed DD-RO incorporates several key innovations to enhance performance. First, a pseudo-differential current-balancing integrator (PD-CBI) significantly extends the linear input range, whereas its intrinsically limited common-mode input range and CMRR are …

A 415 μW 2.4 GHz Receiver With Third-Harmonic Time-Interleaved Passive Mixer and Reconfigurable AFIR Filter for IoT Applications

A 415 μW 2.4 GHz Receiver With Third-Harmonic Time-Interleaved Passive Mixer and Reconfigurable AFIR Filter for IoT Applications 150 150
Author(s): Zongle Ma, Yicheng Chen, Qing Li, Kai Li, Kaixue Ma, Keping Wang

Abstract:

This article presents a 2.4 GHz receiver with a third-harmonic time-interleaved passive mixer and reconfigurable analog finite-impulse-response (AFIR) filter. To improve linearity while maintaining low power consumption, a 6-path third-harmonic time-interleaved mixer with a 6-phase non-overlapping local oscillator (LO) is proposed, employing capacitive stacking and charge sharing techniques to enhance in-band …

Abstract:

Targeting the wireless power transfer (WPT) to implantable medical devices (IMDs), this work presents a 6.78 MHz single-stage dual-output (SSDO) regulating rectifier. It can support the simultaneous charging of both outputs ( $V_{\text {OUT1}}$ and $V_{\text {OUT2}}$ , $V_{\text {OUT1}} \gt V_{\text {OUT2}}$ ) in a half cycle, rather than …

A Wide-Dynamic-Range Photovoltaic Energy Harvester With Adaptive Power-Scalable MPPT Control and Direct Power-to-Digital Converter

A Wide-Dynamic-Range Photovoltaic Energy Harvester With Adaptive Power-Scalable MPPT Control and Direct Power-to-Digital Converter 150 150
Author(s): Yuyan Liu, Huajun Zhang, Mustafa Becermis, Jieyu Liao, Mohit Dandekar, Kofi A. A. Makinwa, Qinwen Fan

Abstract:

This article presents a photovoltaic energy harvester (PVEH) that achieves high maximum power point tracking (MPPT) efficiency and power conversion efficiency across a $100~000{\times }$ input power dynamic range (DR) (from $10~{\mu }$ W to 1W). Wide-dynamic-range operation is challenging due to the inherent tradeoff between MPPT accuracy and controller power consumption. …

Author(s): Samyak Chakrabarty, Vinod Jacob, Mohammadreza Zeinali, Georgios Karfakis, Siyun Qiao, Ziyi Guo, Puneet Gupta, Subramanian Iyer, Sudhakar Pamarti

Abstract:

Compute-in-memory (CiM) accelerators perform matrix vector multiplications (MVMs) directly inside memory arrays, reducing data movement and improving both energy efficiency and throughput for artificial intelligence (AI) workloads. To reduce the number of conversions, recent designs use multibit compute cells. Nevertheless, practical multibit CiM still faces a tension among accuracy, efficiency, …
