1. A digitally controlled grounded inductor simulation circuit, comprising:
an operational amplifier (OP-AMP),
a digitally controlled current amplifier (DCCA),
a voltage buffer,
two resistors, and
a capacitor,
wherein the digitally controlled grounded inductor simulation circuit allows adjustment of an equivalent inductance value CR1R2/A through programming a digitally controlled current gain A of the DCCA, by a computer system coupled to the digitally controlled grounded inductor simulator circuit, and
wherein C is a capacitance of the capacitor, R1 is a resistance of a first resistor, and R2 is a resistance of a second resistor.
