How is transimpedance gain calculated?
The transimpedance amplifier uses an op-amp and a feedback resistor to generate an output voltage that is proportional to an input current. The magnitude of the gain is equal to the feedback resistance, and since inversion occurs, the circuit’s transfer function is \( V_{OUT} = – I_{IN} \times R_F \).
What is BiMOS operational amplifier?
The CA3140 is a BiMOS op-amp that combines the benefits of PMOS transistors with bipolar transistors on a chip. These operational amplifiers are gate-protected PMOS transistors within the circuit. These ICs provide high-speed performance, extremely high input impedance & low input current.
How is transimpedance amplifier calculated?
As the input impedance of the op-amp is very high, the current start to flow through the feedback resistor and the output voltage is dependable on the feedback resistor value times the current is flowing, governed by the formula Vout = -Is x R1 as we discussed earlier.

What are the 2 types of transistors?
Transistors typically fall into two main types depending on their construction. These two types are bipolar junction transistors (BJT) and Field Effect Transistors (FET).
What are the two main types of transistor?
Is PNP normally open or closed?
PNP – (PNP transistor) NO – normally opened, that means there is no voltage on the output while the sensor is not actuated (see picture, PNP sensor output connector is no. 4).
