Digital post-correction on dynamic nonlinearity in GaN HEMT track-and-hold sampling circuits
compound semiconductor integrated circuit symposium, pp. 1-4, 2017.
This paper introduces the recent development of GaN HEMT track-and-hold sampling circuits (THSCs) with a digital post-correction (DPC) technique for emerging applications. Compared to THSCs in silicon technologies, GaN THSCs achieve 20–30 dB higher signal-to-noise ratio (SNR) for a given bandwidth. Nevertheless, GaN THSCs suffer from dyna...More
