The Research of the New Digital Equivalent Inductor

Abstract:

To meet the requirements of scientific research personnel on wide range and high-precision variable inductor. The new digital inductor is based on the impedance converting circuit. The new active impedance converting circuit is formed by integration operational amplifiers, a small amount of resistance and capacitance. Through control of the switching circuit part line, thus producing the equivalent pure inductance. Experimental results show that using digital potentiometer and analog switches adjust circuit resistance to adjust the inductance value. So that digital equivalent inductance has certain advantages in the circuit experiment debugging and inductance adjustable electronic products.
