WebMay 13, 2016 · The resistor, fabricated with the zinc diffusions already used for avoiding premature edge-breakdown, promptly reduces the avalanche current to a low value (~100 μA) in less than 1 ns, while an active circuit completes the quenching and enforces a well-defined hold-off. WebIn modern CMOS and BiCMOS technologies, the diffused or ion-implanted resistors are widely used devices. One important source of errors in the accurate analog circuit simulation is the variation of resistance respect to applied voltage for diffused or ion-implanted resistors. This paper analyzes the electrical properties of the diffused resistors, and …

WebResults indicate that typical diffused resistors are quite invulnerable to ionizing radiation. Design guidelines to achieve optimum hardness are implied. Initial findings of radiation experiments performed on a diffused resistor test chip are reported. WebIn the right third of the "Resistance Structures" region there are eight diffused resistors, four from diffusion #1 and four from diffusion #2. The diffusion #1 resistors and the diffusion #2 resistors are identical (except that they were formed during different diffusions). The straight resistors are 20 μm wide with lengths of 400 and 800 μm. childcare careers scotland
