The model of the SiPM amplifier is a system of 24 equations in 24 variables that has been linearized so that it can be solved by MATLAB.
== Parameters and variables ==
The MATLAB model has a number of parameters and variables to describe the amplifier circuit, including the 24 unknowns, 4 inputs, and numerous constants.
=== Input parameters ===
There are four input parameters:
* Input current: <math>I_{in}</math> (A)
* Bias voltage: <math>V_b</math> (V)
* Power voltage: <math>V_c</math> (V)
* Frequency: <math>f</math> (Hz)
=== Unknown variables ===
There are twenty-four unknown variables. The locations (and directions in the case of currents) are labeled on the circuit diagram.
* Node voltages: <math>V_1, V_2, V_3, V_4, V_5, V_7, V_{out}</math>
* * Note: there is no <math>V_6</math> on this circuit; it was a redundant variable with <math>V_c</math>.
