Circuit having adjustable capacitance for voltage controlled oscillator as for compact discs, has two parallel capacitor units whose capacitance is governed by two separate applied voltages

摘要

A circuit having an alterable capacitance comprises two parallel part capacitor systems (Cdc1,Cdc2,TK1,TK2) whose capacitance depends on the applied voltages (U1,U2). There is a device to adjust these voltages. - Independent claims are also included for the following: - (A) an operating process for the above;and - (B) a computer program for this process
