Amplifier – Simulation and Results

First started with constructing constant current source using PNP transistor with 9V supply voltage.

CONSTANT CURRENT SOURCE:

voltage reading:    3.32V                                               current reading:332mA

AMPLIFIER:
Added one more transistor on NPN in the circuit with the same supply voltage of 9V and input signal of 0.2V.

Simulation Result:

Red –> Amplified Output Voltage

Green –> Input Voltage

Schematic diagram:

In order to increase the gain of the Amplifier, added one capacitor C1 parallel with R6 resistor.
