Abstract:

Zero-knowledge proof (ZKP), one of the most popular privacy-preserving schemes, enables the prover to convince the verifier of a certain statement’s correctness without leaking any private information. Among them, the Pairing-based succinct non-interactive argument of knowledge (zkSNARK), like Groth16 and Plonk, featuring succinct proof size and constant-time verification, is …

A Coherent Polar Phase-Tracking Receiver With High ACR and Relaxed I/Q Generation

A Coherent Polar Phase-Tracking Receiver With High ACR and Relaxed I/Q Generation 150 150
Author(s): Xuansheng Ji, Liqun Feng, Qianxian Liao, Woogeun Rhee, Zhihua Wang

Abstract:

This article presents a coherent polar phase-tracking receiver (PT-RX) for low-power Internet-of-Things(IoT) applications that supports Gaussian frequency-shift keying (GFSK), quadrature amplitude modulation (QAM), and amplitude phase shift keying (APSK). Existing single-path closed-loop receivers achieve low power but suffer from a fundamental tradeoff between loop stability and adjacent channel rejection (…

A −248-dB FOMref CS-Fusion PLL Architecture Combining the Advantages of PFD-CP PLLs and Sampling PLLs in a Single Loop

A −248-dB FOMref CS-Fusion PLL Architecture Combining the Advantages of PFD-CP PLLs and Sampling PLLs in a Single Loop 150 150
Author(s): Junyuan Su, Yuxuan Hu, Zherui Zhang, Lei Wang, Yuncai Zhuang, Fei Song, Jiayoon Ru

Abstract:

This article introduces a CP-sampling (CS)-fusion PLL architecture that combines the advantages of PFD-CP PLLs (robust and speedy locking) and sampling PLLs (low jitter/power) in a single loop. The PFD sends pulsewidth-modulation (PWM) pulses to a merged $mathbf {G_{m}}$ /CP (GCP) block so that the phase error …

A 112-Gb/s PAM4 Receiver With a Phase Equalization AFE in 7-nm FinFET

A 112-Gb/s PAM4 Receiver With a Phase Equalization AFE in 7-nm FinFET 150 150
Author(s): Huanan Guo, Yufeng Yao, Xiang Gao

Abstract:

To reduce the bit-error-rate (BER), equalizers are implemented in high-speed SerDes receivers (RX) to compensate for channel insertion loss and mitigate intersymbol interference (ISI). Conventional analog front-end (AFE) designs primarily focus on amplitude gain while neglecting the influence of phase shift. This brief presents a phase equalization (PEQ) AFE design …
