The MASDA-X chip - A new multichannel ASIC for readout of pixelated amorphous silicon arrays

PDF Version Also Available for Download.

Description

The MASDA-X chip is designed specifically for reading out large amorphous silicon pixel arrays used in medical imaging research. Instrumenting these arrays requires a set of digital row address- ing chips to sequentially select the pixel rows for readout, and a set of column readout chips to collect and process the analog charge transferred to each column by the selected pixels. A 32 channel column readout chip, MASDA-R, has previously been designed and successfully imple- mented by Fermilab and the University of Michigan. However, new arrays require an updated readout chip design with much tighter input channel pitch for direct ... continued below

Description

The MASDA-X chip is designed specifically for reading out large amorphous silicon pixel arrays used in medical imaging research. Instrumenting these arrays requires a set of digital row address- ing chips to sequentially select the pixel rows for readout, and a set of column readout chips to collect and process the analog charge transferred to each column by the selected pixels. A 32 channel column readout chip, MASDA-R, has previously been designed and successfully imple- mented by Fermilab and the University of Michigan. However, new arrays require an updated readout chip design with much tighter input channel pitch for direct mating to arrays. A new 128 channel chip, MASDA-X, has been designed at Fermilab. This chip incorporates performance improvements along with tighter channel pitch. MASDA-R was designed in the H. P. 0.8 micron process, which will no longer be available. Therefore, MASDA-X has been designed in the H. P. 0.5 micron 3.3V process.
