An Ultrasonic Sensor IC for Automotive Parking Assist With Module ID Detection

This article presents an integrated circuit (IC) for automotive parking assistance, which performs ultrasonic time-of-flight (ToF) ranging and module identification. The IC integrates a bidirectional transducer driver for a center-tapped transformer, a low-noise high-gain analog front-end (AFE) with programmable gain a...

High-Performance On-Chip Low-Dropout Regulators for HBM and SoC Power Integrity: Architectures, Metrics, and Design Perspectives

The rapid growth of artificial-intelligence (AI) and high-performance computing workloads has reshaped the power-delivery requirements of high-bandwidth memory (HBM), neural processing units (NPUs), and advanced systems-on-chip (SoCs). These platforms draw large currents that vary rapidly at aggressively scaled supply...
