:<math> B_1 = -A . E_2 + v_{offset} </math>
where A is a gain parameter with a default unit value and v<sub>offset</sub> is an arbitrary offset voltage with a default zero value. The relationship between the input and output voltages is given by" :<math> v_{out}(t) \approx -A . \frac{ dv_{in} }{dt} + v_{offset} </math>
