该论文提出了一种12.8GS/s的亚采样ADC前端,在22nm FDSOI工艺下实现了38GHz输入带宽和>39dB SNDR,覆盖1-32GHz频率范围。解决了毫米波RF采样中高频前端带宽与信号保真度的挑战,支持X波段到Ka波段的多通道灵活接收。
with the crowded wireless spectrum results in a trend towards millimeter-wave frequencies. RF-sampling architectures offer advantages in terms of flexibility, simplicity and robustness. However, presenting the ADC directly with tens of GHz at the input poses significant challenges especially to the front-end, leading to a demand for high-bandwidth- and fidelity implementations. This work targets RF-sampling of X-band to Ka-band frequencies while maximizing signal purity and a Nyquist bandwidth of 6.4GHz to allow flexibility and multi-channel reception, but minimizing system complexity and data-rate overhead. The focus is on the lower Ka-band around 27 to 31GHz used for high-throughput Earth-to-Satellite communication applications.
