This paper proposes a model for calculating statistical gate-delayvariation caused by intra-chip and inter-chip variability. As thevariation of individual gate delays directly influences the circuit-delayvariation, it is important to characterize each gate-delay variationaccurately. Furthermore, as every transistor in a gate affectsthe transient(More)
This paper proposes a model to calculate statistical gate-delay variation caused by intra-chip and inter-chip variabilities. Our model consists of a statistical transistor model and a gate-delay model. We present a modeling and extracting method of transistor characteristics for the intra-chip variability and the inter-chip variability. In the modeling of(More)
This paper presents a design, simulation, implementation and measurement of a novel microstrip meander patch antenna for the application of sensor networks. The dimension of the microstrip chip antenna is 15 mm times 15 mm times 2 mm. The meander-type radiating patch is constructed on the upper layer of the 2 mm height substrate with 0.0 5 mm height(More)
— This paper proposes a model to calculate statistical gate-delay variation caused by intra-chip and inter-chip variabili-ties. The variation of each gate delay directly influences the circuit-delay variation, so it is important to characterize each gate-delay variation accurately. Every transistor in a gate affects transient characteristics of the gate, so(More)
