SiPM Amplifier

The silicon photomultipliers (SiPM) we are using in our experiment were purchased from Photonique. Photonique also supplies analog electronics boards to amplify the signals from the SiPMs. This page discusses the analysis and modeling of the amplifier circuit.

The circuit diagram

The amplifier circuit diagram shown here was developed through combining the diagram supplied by Photonique (lacking component values, and having several extra components) and the physical circuit (having most components labeled).

Resistor values
$R_{1}$	$100k\Omega$
$R_{2}$	$10k\Omega$
$R_{3}$	$5.6k\Omega$
$R_{4}$	$2k\Omega$
$R_{5}$	$1k\Omega$
$R_{6}$	$51\Omega$
$R_{7}$	$240\Omega$

Transistors
Part	On-chip label	SMD Component
$VT_{1}$	E2P (1717)	Philips BFS 17A
$VT_{2}$	W1S (13)	Philips BFT 92

The capacitors are unlabeled on any diagram.
