Soft-x-ray CCD imagers for AXAF
Summary
Summary
We describe the key features and performance data of a 1024 x 1026-pixel frame-transfer imager for use as a soft-x-ray detector on the NASA X-ray observatory Advanced X-ray Astrophysics Facility (AXAF). The four-port device features a floating-diffusion output circuit with a responsivity of 20/spl mu/V/e/sup -/ and noise of about...
Dynamic suppression of interface-state dark current in buried-channel CCDs
Summary
Summary
It is shown that the time dependence of the carrier generation rate at a depleted surface can be exploited to completely suppress interface-state dark current in buried-channel charge-coupled devices (CCDs). When a surface is switched from an inverted to a depleted state, the generation current recovers with a time constant...
