In a integrator circuit, assume R2 = 80 kΩ and the amplitude of the input voltage is 100 mV. Calculate the amplitude of the output voltage in mV. Hint: The Amplitude of the output voltage is the input amplitude times the voltage gain.
VCC = 12V
VEE = -12V
R1 = 10 KΩ
The voltage gain of an integrator circuit is given by the formula:
Gain = -R2/R1
Substituting the given values, we get:
Gain = -(80 kΩ)/(10 kΩ) = -8
Therefore, the amplitude of the output voltage is:
Amplitude of output voltage = Gain x Amplitude of input voltage
= -8 x 100 mV
= -800 mV
Note that the output voltage amplitude is negative, indicating that the output signal is inverted with respect to the input signal. Also, the output voltage amplitude would continue to increase over time if the input voltage is a constant (DC) voltage, as the integrator circuit integrates the input signal over time.
