Scheinwiderstandsvorrichtung

摘要

An impedance device adapted to represent various types of impedance which includes a two-transistor circuit equivalent to a single transistor with a common base current amplification factor greater than one and a predetermined impedance element or circuit, and circuits using such an impedance device. This impedance device represents an impedance corresponding to the impedance of the impedance element or circuit multiplied by -( alpha 0-1) where alpha 0 is the equivalent common base current amplification factor of the equivalent single-transistor circuit. One of the circuits using the impedance device is an oscillator which is constructed without an inductance element. Another of the circuits is an inductor having a pure inductance and which is constructed without using any inductance element.
