Paper Abstract

In order to improve the uniformity and yield of the focal plane arrays being used in Cincinnati Electronics infrared camera systems, the multiplexer is being upgraded to include a feedback enhancing buffer amplifier in its unit cell. A test die containing variations of a buffered direct injection circuit, along with some of its constituent parts, has been fabricated and tested. The test results have been compared with predicted performance from SPICE modeling of the circuit, and generally good agreement has been obtained. The results indicate with only a modestly sized buffer amplifier, sufficient performance improvement can be obtained to significantly improve the device yield for the infrared camera focal plane array.
