4. (a) Consider the differentiating operational amplifier circuit. The feedback resistor is
220 k2, and the input capacitor is 22 uF. If a ramp voltage applied across the input
which is -2 V after one second. It increases by -2 V every second for six
seconds. Calculate the output voltages of the amplifier for each second after the
ramp
voltage on the input has been applied. From this draw a graph of output voltage
against time and compare this to the input voltage.
(b) Consider the integrating operational amplifier circuit. The input resistor is 125 kN,
the feedback capacitor is 12 uF, and the voltage across the input is constant at
-5 V. Calculate the output voltages of the amplifier for each second after the input
voltage has been applied, up to 6 seconds. From this draw a graph of output voltage
against time and compare this to the input voltage.
