Pixels for curved focal plane arrays using organic photosensitive devices

Autor: Munira Raja, Ruth Wanjau, Bhaskar Choubey

Publikováno v: 2017 IEEE SENSORS.

Typical focal plane arrays are almost always flat (including CMOS and CCD image sensors), which then requires complex and heavy lens assembly. This is in contrast to the human eye, which uses a curved focal plane array, the retina. Manufacturing a cu

Design of a high gain organic comparator for use in low-cost smart sensor systems

Autor: D. Donaghy, Munira Raja, R. W. Wanjau

Publikováno v: 2015 11th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME).

This paper presents novel designs of a 3-stage organic comparator, a key building block of an organic analogue-to-digital converter (ADC), for integration in low-cost smart sensor systems. The designs adopt a pseudo-PMOS configuration so as to allow

Electrical conduction processes in semiconducting organic films has been a subject of great debate for a number of decades. There is a general agreement that the energy band models are inappropriate, for describing the electronic conduction in such m

We have approximated the tail of the Gaussian distribution of states of organic semiconductors with an exponential function. We have used this approach to calculate the carrier concentration in organic materials, and subsequently the charge distribut
