Critical to the success of analog synthesis in VASE is the accuracy of analog performance estimation at various levels of abstraction. The analog performance estimator (APE) in VASE is used during mixed signal partitioning, analog behavior synthesis as well as analog circuit synthesis. APE is capable of accepting the design parameters (bias current) of an analog component as input and determine...

The sole cell type (the amoebocyte) found in the coelomic fluid of the horseshoe crab, Limulus polyphemus can be stimulated to become motile by extravasation or trauma. Motility was studied using time-lapse microcinematography and direct microscopic examination of cells in tissue culture and in gill leaflets isolated from young animals. Phase-contrast and Nomarski differential-interference cont...

Addition of plasma to the physiologic salt solution in which helical strips of vascular smooth muscle were suspended caused the muscle to contract. The plasma was obtained from dog arterial blood which, extracorporeally, had been in contact only with siliconized polyethylene in the cold. The strips were from large and small vessels from several sites in rabbit and dog. The contractions were rep...

Mixed-signal AI accelerators offer the possibility of higher energy efficiency for moderate resolution computations compared to their digital counterparts. All-analog implementations, where all operations are performed in analog domain, can further improve this advantage. An efficient multiply-accumulate cell all-analog neural layer processing macros is presented. The proposed two-quadrant mult...
