One-Cycle-Balance Control in Buck Converters for Consecutive Load-Step Events

One-Cycle-Balance Control in Buck Converters for Consecutive Load-Step Events 150 150

Abstract:

One-cycle-balance (OCB) response represents the optimal load-transient response for buck converters, maximizing system energy efficiency and robustness. While prior art has demonstrated OCB response for single load-step events, it fails in consecutive transients, which are prevalent in modern applications. This work overcomes these limitations by introducing an OCB controller that …

A 256-Channel Solid-State Nanopore Readout Array With 193-pA TIAs and Event Detection at 1-MHz in 65-nm CMOS 150 150

Abstract:

Solid-state nanopore single-molecule sensing aims to replace the commercially available biological nanopores. Array sizes have remained limited due to the area and power consumption of the transimpedance amplifiers (TIAs), thus preventing throughput and cost scaling. This article presents a 256-channel readout array for solid-state nanopore single-molecule sensing in 65 nm CMOS. …

Medusa: A Scalable Quantum-Inspired k-SAT Solver With Make and Break Feedback

Medusa: A Scalable Quantum-Inspired k-SAT Solver With Make and Break Feedback 150 150

Abstract:

Boolean satisfiability (SAT or $k$ -SAT, $k ge 3$ ) is a binary combinatorial optimization problem (COP) that is challenging for traditional classical computing to address in polynomial time. Quantum and quantum-inspired systems have been touted to tackle these and similar nondeterministic polynomial-time (NP) problems. This work describes Medusa, a quantum-inspired $k$ …

A 42-Gb/s PAM-3 Transmitter With a CML Driver and a Dual-Mode Encoder for Process-Variation-Tolerant Middle-Level Generation

A 42-Gb/s PAM-3 Transmitter With a CML Driver and a Dual-Mode Encoder for Process-Variation-Tolerant Middle-Level Generation 150 150

Abstract:

This letter presents a 42-Gb/s differential pulse-amplitude modulation (PAM-3) transmitter using a current-mode logic (CML) driver and a dual-mode 3B2T encoder for process-variation-tolerant middle-level (M-level) generation. The encoder selects between two M-level encoding schemes to compensate for load-resistor and driver-current-path mismatches with minimal logic overhead, reducing the standard …

A 4-GS/s 53.5-dB SNDR 12.9 fJ/conv. TI-SAR ADC With Capacitive Nonlinearity Compensation and Dual-Mode Offset Calibration

A 4-GS/s 53.5-dB SNDR 12.9 fJ/conv. TI-SAR ADC With Capacitive Nonlinearity Compensation and Dual-Mode Offset Calibration 150 150

Abstract:

Successive approximation register (SAR) analog-to-digital converters (ADCs) often employ dual-mode dynamic comparators to achieve both high speed and low noise. However, under low-supply operation, offset drift from mode transitions and degraded front-end linearity due to limited signal headroom become critical challenges. To address these issues, an adaptive current-injection scheme suppresses …
