We propose a new AlN crystal growth method using Fe-based fluxes. AlN single crystals with a thickness of 67–212 µm were epitaxially grown on an AlN bulk substrate by a solution growth method using type 430 ferritic stainless steel flux. The full

A selectively activated 8 $\times $ time-domain (T-domain) latch interpolation is proposed for low-power high-speed flash analog-to-digital converters (ADCs). Flash ADCs with T-domain latch interpolation perform voltage-to-time (V-to-T) and time-to-d
