A 16× Interleaved 32-GS/s 8b Hybrid ADC With Self-Tracking Inter-Stage Gain Achieving 44.3-dB SFDR at 20.9-GHz Input 150 150

Abstract:

This article presents a 32-GS/s 16-channel hierarchical time-interleaved (TI) hybrid analog-to-digital converter (ADC). The prototype utilizes the intrinsic high-speed quantization of time-domain (TD) ADC to reduce the interleaving factor. By incorporating hierarchical sampling and a cascode sampler, the compact TI-ADC achieves 44.3-dB spurious-free dynamic range (SFDR) at 20.9-GHz input. …

A 40-GS/s 8-bit Time-Interleaved ADC Featuring SFDR-Enhanced Sampling and Power-Efficient Time-Domain Quantization in 28-nm CMOS 150 150

Abstract:

This article reports a 40-GS/s 8-bit time-interleaved (TI) time-domain (TD) gated-ring-oscillator analog-to-digital converter (GRO-ADC). An interleaving number of 32 is achieved with a single-channel 8-bit GRO-ADC operating at 1.25 GS/s, leading to a low front-end design complexity compared to recently published arts. The sampling front end employs a linearity-enhanced boosted …
