Abstract:

This article proposes a hybrid magnetic current sensor achieving a 15-MHz bandwidth within a compact 2.7-mm2 area. To mitigate the pole–zero mismatch inherent in the two-stage integrator topology, a dual-output Gm-C integrator with subtractor-based compensation is proposed, achieving a ±0.8% local gain non-uniformity. A wideband feedforward ripple suppression scheme cancels …

Abstract:

This article presents a type-III wide-bandwidth ring-oscillator-based analog phase-locked loop (PLL) optimized for low-jitter performance in noisy supply environments. The design uses an 812.5-MHz reference frequency and a high-gain sampling phase detector to achieve a closed-loop bandwidth over 100 MHz, effectively reducing the intrinsic phase noise of the ring oscillator. To …
