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.
