Abstract:
This article presents a 436–472GHz four-element intermediate-frequency (IF) beamforming phased-array receiver fabricated in 65-nm CMOS, targeting scalable terahertz (THz) phased-array systems. The proposed receiver adopts a two-step mixing scheme to reduce the area overhead of the IF beamforming implementation, thereby enhancing the array scalability at THz frequencies. Each receive channel …
