A 16 V-Output Switched-Capacitor Sigma Converter With 180 ns Transient Response and 94% Efficiency for LiDAR Receivers

A 16 V-Output Switched-Capacitor Sigma Converter With 180 ns Transient Response and 94% Efficiency for LiDAR Receivers 150 150

Abstract:

This article presents a step-up switched-capacitor (SC) sigma converter with fast transient, high efficiency, and high accuracy for light detection and ranging (LiDAR) receiver applications. The proposed sigma converter combines an unregulated SC converter in the high-voltage (HV) domain and a low-dropout (LDO) regulator in the low-voltage (LV) domain, achieving …

A 4 × 224 Gb/s Single-Ended PAM-4 Transceiver Front-End With Noise Suppression Technique and Cascaded Equalizers in 130-nm SiGe BiCMOS

A 4 × 224 Gb/s Single-Ended PAM-4 Transceiver Front-End With Noise Suppression Technique and Cascaded Equalizers in 130-nm SiGe BiCMOS 150 150

Abstract:

A dc-coupled analog single-ended (SE) transceiver (TRX) front-end supporting 224 Gb/s/lane is presented. It features SE-to-differential (S2D) and differential-to-SE (D2S) conversion, power-efficient broadband analog equalization, and noise suppression. Both the transmitter and receiver front-ends adopt pseudodifferential structures with dual-loop regulators to achieve a high power supply rejection …

A Two-Stage 12–1-V Converter Featuring Regulated Resonant SC Regulators and Collaborative Control Scheme

A Two-Stage 12–1-V Converter Featuring Regulated Resonant SC Regulators and Collaborative Control Scheme 150 150

Abstract:

In the field of power converters for data centers, the two-stage architecture has received widespread attentions due to its various advantages. Especially, the switched-capacitor voltage regulator (SCVR) becomes popular as the second-stage converter owing to its high efficiency and power density. However, the SCVR suffers from poor voltage regulation and …

A Fast Transient Response Fully Integrated LDO With a Novel Resetting Oscillator Control Method

A Fast Transient Response Fully Integrated LDO With a Novel Resetting Oscillator Control Method 150 150

Abstract:

This article introduces a novel resetting oscillator regulator (ROR) control method for low-dropout (LDO) regulators, designed to achieve fast settling times for both load and reference input steps. The proposed ROR integrates a high-speed loop that independently functions as an oscillator in a closed-loop configuration, along with a separate high-rate …
