Abstract: This article presents a fractional-N sampling type-I phase-locked loop (PLL). To overcome the impairments of a conventional type-I PLL, namely the frequency-tuning-dependent time offset and the narrow range of the sampling phase detector (SPD), which… read more here.

Abstract: This paper reports an active-buffer-free type-I sampling phase-locked loop (S-PLL). We innovate a fully-passive sampling phase detector with passive-gain multiplication after the sampler, resulting in a stably-boosted PD gain and better linearity. Together with a… read more here.
