Abstract

The invention relates to a negative capacitance device, a negative inductance device, and a circuit including the same. According to one embodiment, a negative capacitance device is provided having afirst terminal and a second terminal. The negative capacitance device includes: a first operational amplifier having a first non-inverting input terminal connected to the first terminal of the negative capacitance device, a first inverting input terminal connected to the second terminal of the negative capacitance device, and a first output terminal; a first capacitor connected between the first non-inverting input terminal and the first output terminal of the first operational amplifier; a first resistor connected between the first inverting input terminal and the first output terminal of thefirst operational amplifier; and a second resistor connected between the first inverting input terminal of the first operational amplifier and the second terminal of the negative capacitance device.

Description

technical field [0001] The present invention generally relates to the field of electronic components, and more particularly, to a negative capacitance device and a negative inductance device, and a circuit including at least one of them. Background technique [0002] Compensation is a matching method often used in circuits, so that the circuit system can work in a reasonable range to a greater extent. Among them, the compensation of reactance or susceptance is a very important compensation method in impedance matching, in order to achieve the transmission of electric energy, Store, release and absorb. The usual reactance or susceptance compensation components are traditional capacitors or inductors, which have positive capacitance or inductance values, but if the circuit to be compensated already has redundant positive capacitance or positive inductance, traditional capacitors or inductors cannot be used. Achieve their goals. The impedance phases of inductors and capacitor...
