Digitally-controlled grounded inductance
Stephan I. Koutzarov · International Journal of Electronics · 1990
A circuit with two amplifiers for simulation of grounded inductance is given. The inductance can be controlled digitally or manually, by the gain of one of the amplifiers, while the quality factor is constant. The influence of the real amplifier parameters is considered. Two circuits for linear digital control are given. Error analysis and a design procedure are included.
