Designing a Capacitance Multiplier as a Power Supply Filter
Simple capacitor multiplier with a transistor . ... If you are driving the capacitance multiplier at a lower input voltage, then you need to apply a lower collector-base voltage (i.e., R2 > R1) to ensure the transistor enters saturation. If the input voltage is sufficiently high, you can set the output voltage by adjusting the values of R1 and R2.
Capacitance Multiplier
For a given input voltage, the rate of change in voltage in C1 is the same as in C2, because C2 has 100 times the capacitance to make up for 1/100th the current. So the voltages across the two capacitors are the same, but the currents are not. The op-amp causes the – input to be held at the same voltage as the voltage across C1.
