A tunable grounded positive and negative active inductor simulator and impedance multiplier circuit and a method for implementing the tunable grounded positive and negative active inductor simulator and impedance multiplier circuit are described. The circuit includes one second generation voltage-mode conveyor circuit (VCII+), a voltage source configured to generate an output current, a first impedance, a second impedance and an operational transconductance amplifier OTA. The first impedance is connected between the voltage source and the positive VCII+ input terminal, Y. The second impedance is connected between the second output terminal and a ground terminal. The OTA is configured to have a transconductance gain. The circuit is configured to be tuned by a selection of values for the first and second impedances.

An integrated circuit may include one or more circuits coupled to capacitance multiplier circuitry. The capacitance multiplier circuitry may include a capacitor, fixed and tunable resistances, and a transconductance circuit. The tunable resistance can be adjusted to control the overall capacitance of the capacitance multiplier circuitry. The transconductance circuit may include a transistor having a drain terminal coupled to a first electrical component and a source terminal coupled to a second electrical component. The first electrical component may be a diode-connected transistor, a direct shorting wire, a resistor, an inductor, or a current source. The second electrical component may be a current source, a direct shorting wire, a resistor, an inductor, or another diode-connected device. Configured in this way, the capacitance multiplier circuitry can provide a large adjustable amount of capacitance without a voltage drop and without consuming a large amount of power.
