Abstract :
Electronic tuning for AM radios becomes possible with today´s varactor diodes. The large capacitance values available permit smaller AM radios and remote tuning. Utilization of varactor diode tuning, however, demands extreme voltage stability, since small changes in the tuner reference voltage will change the diode capacitance and therefore the resonant frequency.
