Introduction:Belle II
Introduction: KLM Electronics
Pre-Amp schematic
● Differential Amplifier● Common Base Amplifier
Project Goals● Characterize the current version of the pre-amp
● Simulate the pre-amp
○ Recreate the characteristics observed from
experiment
○ Modify and simulate changes to the pre-amp
● Make modified pre-amp and test

Simulated pre-amp in SPICE
Simulated characteristics from pre-amp (R=100Ohms), Gain ~ 2
Issues and Challenges
● Gain of the pre-amp
● Litmus test for simulation
● Initial stage section
● Time
Revised Schedules ● Nov. 30th: Analyze different stages of preamp in SPICE, study
common-base amplifiers
● Dec. 1st: Vary components of preamp in SPICE and observe gain.
● Dec. 5: Finish construction and test the modified pre-amp.
● Dec. 6: Prepare for presentation
● Dec. 7: Presentation Day
Expected Deliverables● Realistic
○ Reasonably accurate SPICE simulation of the pre-amp
○ Initial prototypes on possible modifications of the pre-amp
● Optimistically
○ Reasonably accurate SPICE simulation of the pre-amp
○ A modified pre-amp with significantly improved dynamical range
