Author(s): Peizhe Li, Danfeng Zhai, Qi Liu, Chixiao Chen

Abstract:

This work proposes a rapid digital amplification (RDA) with residue-aware reference, offering an equivalent open-loop (OL) gain enhancement of 25 dB and reducing the interstage gain error (ISGE)-induced SNR degradation by 20 dB, with an extra amplification latency of only 200 ps. It is implemented in an 800-MS/s 13-b two-way time-interleaved (…

A High-Efficiency Magnetoelectric Power Link With a Load-Adaptive CMOS Rectifier for Miniaturized Implants

A High-Efficiency Magnetoelectric Power Link With a Load-Adaptive CMOS Rectifier for Miniaturized Implants 150 150
Author(s): Yasemin Engür, Mingxiang Gao, Niels Kuster, Mahsa Shoaran

Abstract:

Miniaturized biomedical implants are currently constrained by limited wireless power transfer (WPT) efficiency under load variation and spatial misalignment. This work presents a custom magnetoelectric (ME) power link incorporating a load-adaptive CMOS rectifier to address these challenges. By employing a current sensing control loop for dynamic switch sizing and delay …

A 1.1-nJ/Conversion RC-Discharge-Based Resistance Sensor With ±0.65% (3σ) 1 -Point Trimmed Inaccuracy in 0.18-μm CMOS Technology

A 1.1-nJ/Conversion RC-Discharge-Based Resistance Sensor With ±0.65% (3σ) 1 -Point Trimmed Inaccuracy in 0.18-μm CMOS Technology 150 150
Author(s): Mu Wu, Yihang Cheng, Xingli Cui, Sining Pan, Huaqiang Wu

Abstract:

This letter presents an energy-efficient RC discharge-based sensor readout circuit for sub-kilo-ohm resistance measurements. An SAR logic is implemented to adjust the DAC capacitor array to equalize the RC time constants of the resistance-sensing and DAC branches, thereby eliminating the high static current required to bias the small sensing resistor. …
