摘要

提出了一种22-29 GHz的90 nm块体CMOS超宽带脉冲发射机。该发射机基于连续运行的LC-tank 26 GHz信号与伪高斯基带脉冲的混合。为了最大限度地提高脉冲峰值到峰值电压，单平衡吉尔伯特单元混频器装载了集总平衡器。测量结果表明，在22-29 GHz频段内，脉冲带宽为-10 dB，带宽为5ghz, Vp-p为219 mV。

A 26 GHz UWB CMOS IR-UWB transmitter with on-chip balun

A 22-29 GHz UWB pulse transmitter in 90 nm bulk CMOS is presented. The transmitter is based on mixing of a continuous running LC-tank 26 GHz signal with a pseudo Gaussian base-band pulse. To maximize pulse peak to peak voltage a single balanced Gilbert cell mixer is loaded with a lumped balun. The measured results show a pulse with a -10 dB bandwidth of 5 GHz and a Vp-p of 219 mV within the 22-29 GHz band.
