A voltage controlled oscillator for wide range tuning bandwidth includes a transistor with a voltage tunable resonant circuit connected to an emitter of the transistor and inductive elements connected to the collector of the transistor. Also disclosed are methods of using such compounds in the treatment of at least one CYP17 associated condition, such as, for example, cancer, and pharmaceutical compositions comprising such compounds. In a second mode the telephone caller screening device controls the telephone system by generating an off-hook condition on the pre-existing telephone line to suppress the ring signal from an incoming telephone call to prevent audible ringing of the telephone device. The receptacle is communicatively open to the shaft such that the material or a liquid-material mixture dissolved from at least a portion of the material can flow from the receptacle into the shaft. The device provides a display having improved pixel-driving performance and increased light-emitting area. The modulator also has a means for determination of a signal ; FDEV) which is characteristic of the modulation shift of the modulated signal.
