    Abstract: 시간스큐조정회로(800)는인터리빙방식 ADC(210)의복수의채널들(CH1-CH4)로부터입력신호(201)의일련의샘플들(V(t))을수신하기위한입력을포함한다. 제1 뺄셈기(802)는수신된일련의샘플들(V(t))에서연속샘플들(V(t), V(t+1)) 간의거리들(ΔV)을계산하고, 복수의평균회로들(8300-8304)은인터리빙방식 ADC(210)의각각의쌍의채널들(CH1-CH2, CH2-CH3, CH3-CH4, CH4-CH1)로부터의연속샘플들(|ΔVt1-t2|, |ΔVt2-t3|, |ΔVt3-t4|, |ΔVt4-t1|) 간의거리의평균에각각대응하는복수의제1 평균거리들(μ(ΔVt1-t2), μ(ΔVt2-t3), μ(ΔVt3-t4), μ(ΔVt4-t1))을계산한다. 시간스큐검출회로(802, 803, 804, 810, 820, 830)는제1 평균거리들(μ(ΔVt1-t2), μ(ΔVt2-t3), μ(ΔVt3-t4), μ(ΔVt4-t1)) 각각을복수의채널들(μ(ΔV))로부터의연속샘플들간의거리들의평균과비교함으로써각각의쌍들의채널들(CH1-CH2, CH2-CH3, CH3-CH4, CH4-CH1) 사이의각각의시간스큐들(α(-Δt1+Δt2), α(-Δt2+Δt3), α(-Δt3+Δt4), α(-Δt4+Δt1))을계산한다. 발산제어회로(840)는입력신호(201)와연관된나이퀴스트구역(NZ_Select) 및제1 평균거리들(μ(ΔVt1-t2), μ(ΔVt2-t3), μ(ΔVt3-t4), μ(ΔVt4-t1))에적어도부분적으로기초하여시간스큐들(α(-Δt1+Δt2), α(-Δt2+Δt3), α(-Δt3+Δt4), α(-Δt4+Δt1))의정확도를결정한다.

    Abstract: An embodiment of an apparatus is disclosed. For this embodiment of the apparatus, an interposer (203) has first vias (211). First interconnects (205) and second interconnects (206) respectively are coupled on opposite surfaces of the interposer (203). A first portion of the first interconnects (205) and a second portion of the first interconnects (205) are spaced apart from one another defining an isolation region (220) between them. A substrate (204) has second vias (212). Third interconnects (207) and the second interconnects (206) are respectively coupled on opposite surfaces of the package substrate (204). A first portion of the first vias (211) and a first portion of the second vias (212) are both in the isolation region (220) and are coupled to one another with a first portion of the second interconnects (206).
