A capacitance magnification circuit comprising an amplifier having a positive gain G, a first capacitor having a value C1, and a second capacitor having a value C2. The first capacitor is connected between the input port of the amplifier and an input port of the circuit, the second capacitor is connected between the input and output ports of the amplifier, and the output port of the amplifier is connected to an output port of the circuit. An effective capacitance value C12/ delta is realized when the condition (G-1)C2-C1= delta is satisfied, where delta is an arbitrarily small positive value. |
