Paper Abstract

Good agreement has been found between theoretical models and measured performance for a range of array geometries. A 64 element 80 μm x 140 μm element array with integral MOSFET I.C. buffer pre-amplifiers shows improved source voltage uniformity c.f. a J-FET buffered array and low frequency D* of 1.7 X 108 cm/Hz/W at 40 Hz. The MOSFET array shows reduced degradation of D* at high temperatures, retaining a D* 1 x 108 cm,/Hz/V1 at + 700C across much of the band. A 64 element array has been designed using on-board multiplexers thus greatly reducing the connections needed to run the array.
