— This paper presents an electronically tunable impedance transformer and matching network for RF applications, utilizing thin-film Barium Strontium Titanate (BST) tunable capacitors in an integrated-passive network on sapphire. The impedance transformer can be electronically varied from a 4:1 to 2:1 transformation in a 50 Ohm environment. A slight(More)
Conservative garbage collectors are commonlyused in combination with conventional C programs. Empirically, this usually works well. However, there are no guarantees that this is safe in the presence of \improved" compiler optimization. We propose that C compilers provide a facility to suppress optimizations that are unsafe in the presence of conservative(More)
Historically our paper was important because it demonstrated that it was possible to get useful information about linked data structures in a practical amount of time. At the time of publication , there was some interest in pointer analysis from the theoretical community, but these algorithms were generally impractical. Our paper presented a technique that(More)
