Voltage (mV) 8 6 4 2 0 -2 -4 -6 -8 Figure 22- Graphical analysis of inverting amplifier Analysis of a Non-inverting Amplifier and Measuring its ACL and Phase Shift: First, construction of the circuit seen in Figure 4 was done using color coded resistor values of 15-kΩ for Ri and 120-kΩ for Rf. The resistance of Ri was measured to be 14.8-kΩ and Rf measured to be 117 -kΩ. A load resister was placed at the terminal of the output voltage, which proved to have no effect on the value of the output voltage. The circuit was hooked to an input voltage of ±1V at 100Hz from the function generator, and source voltages of VCC= +15V and VEE= -15V. The closed loop gain for the non- inverting amplifier was then calculated using the gain equation, Equation 8. The gain for the non-inverting amplifier was calculated to 8.905. The experiment was conducted with the input voltage changed from a peak voltage of 2V to 5V. This voltage change caused distortion of the Vout wave as previously seen with the Inverting Amplifier. Inverting Amplifier Analysis Voltage Output 30 Voltage Input
The oscilloscope had the input voltage monitored by channel one and seen modeled by a sin wave with an amplitude equal to Vin. The output voltage was monitored by channel 2. Pictures were taken of the results, see Figure 23 and Figure 24. Figure 23- oscilloscope picture of non-inverting amplifier Figure 24-Distorted voltage output oscilloscope picture 31
