A 108-Gb/s PAM-8 CTLE + FFE Receiver Front-End With 1.4-Vppd Input Range in 28-nm CMOS 150 150

Abstract:

This article presents a 108-Gb/s 8-level pulse amplitude modulation (PAM-8) receiver front-end capable of handling a wide input dynamic range to overcome the signal-to-noise ratio (SNR) versus linearity tradeoff in higher-order modulation schemes. The proposed architecture employs a multi-path continuous-time linear equalizer (CTLE) with a bias-shifting technique, which splits …

A Three-Level Dual-Path Hybrid Buck Converter With Mitigated Capacitive Current and Seamless DVS Across a Wide Output Voltage Range

A Three-Level Dual-Path Hybrid Buck Converter With Mitigated Capacitive Current and Seamless DVS Across a Wide Output Voltage Range 150 150

Abstract:

This article presents a three-level dual-path (TLDP) buck converter tailored for mobile application processors (APs) with a 1.8-V input and 0.4–1.5-V output range. Conventional buck (CB) and multi-level buck (MLB) converters suffer from prohibitive DC resistance ( $R_{\mathrm {DCR}}$ ) losses in compact inductors as load current increases. Although various multi-path …

A Low-Spur Fractional-N DPLL With Analog Pre-Distortion DTC Implementing Second-/Third-Order Calibration

A Low-Spur Fractional-N DPLL With Analog Pre-Distortion DTC Implementing Second-/Third-Order Calibration 150 150

Abstract:

This article presents a low-spur, low-jitter fractional-N digital phase-locked loop (DPLL) employing an analog pre-distortion digital-to-time converter (APD-DTC) to suppress fractional spurs by compensating for both second- and third-order nonlinearities without using complex digital pre-distortion. To support background calibration, a spur-level detection scheme using phase detector gain (PDG) is proposed …

Verifica: Near-Memory Symbolic Interval Computing Formal Neural Network Verification Accelerator 150 150

Abstract:

Formal robustness verification of neural networks is essential for deploying machine learning (ML) systems in safety-critical applications. However, existing verification frameworks are predominantly software-based, incurring prohibitive computational costs and long runtimes, severely limiting scalability and practical deployment. Although symbolic interval analysis enables scalable over-approximate verification, its effectiveness is limited by …
