Abstract :
The authors present their experiences in designing and producing 26000 new charge-integration amplifiers for the Collision Detector Facility (CDF), using surface-mount components. The new amplifiers were needed to instrument 920 new 24-channel CDF RABBIT boards, which are replacing an older design rendered obsolete by increases in the collision rate. Important design considerations were frequency response, physical size, and cost. Compared to the standard cascode, this amplifier has better power supply rejection, higher gain, higher bandwidth, and reasonably good noise figures. Higher than expected amplifier reliability, resulting in an easier checkout task, was an unexpected benefit.<>
