3. Optoelectronic amplification

In this section, the main voltage amplifier circuits are presented. The calculation of the open-circuit voltage gain is developed, while the input impedance and output impedance are simply given.

3.1 Simplified analysis of a non-inverting amplifier circuit

The analysis of a linear AOP circuit, assuming it is perfect, can be carried out very simply using basic electronics theorems.

Consider, for example, the non-inverting amplifier shown in Figure 7 , where the voltage to be amplified is denoted by vin...
