Abstract
The multiple gain pre-amplifier is a three gain channel 0.25 micron CMOS chip matched to the noise and linearity requirements of the electromagnetic calorimeter for CMS. A choice of external feedback components to the first stage amplifier allows the chip to be used for both barrel and end-cap regions of the detector. Details of the design and performance measurements are presented.
