A 60-V High-Linearity Shunt-Based In-Line Current Sensor With DLL-Assisted Dynamic Body-Biasing and High dV/dt PWM Rejection Up to 2MHz

A 60-V High-Linearity Shunt-Based In-Line Current Sensor With DLL-Assisted Dynamic Body-Biasing and High dV/dt PWM Rejection Up to 2MHz 150 150
Author(s): Heng Ma, Huajun Zhang, Yuyan Liu, Qinwen Fan

Abstract:

This article presents a fully integrated shunt-resistor-based in-line current sensor for high-voltage (HV) pulse-width modulation (PWM)-based power systems. Floating-Gm current sensors are effective at rejecting HV PWM common-mode (CM) interference, but their linearity degrades at high CM voltages due to the substrate current-induced body effect (SCBE) in HV laterally …

A Low-EMI, High-DR Class-D Audio Amplifier With Double-Sided Voltage-Boosting Modulation

A Low-EMI, High-DR Class-D Audio Amplifier With Double-Sided Voltage-Boosting Modulation 150 150
Author(s): Jhuang-Wei Cyue, Tai-Haur Kuo

Abstract:

This article presents a digital-input class-D audio amplifier (CDA) that employs a double-sided voltage-boosting (DSVB) modulation scheme, integrating a capacitively coupled chopper amplifier (CCCA) with a single-inductor buck–boost power stage. The CCCA achieves a high dynamic range (DR) due to its very low noise floor and is implemented with …
