ABSTRACT:
An oscillator usable for a TDMA type wireless mobile communication device in which an average current at the communication terminal is decreased. The oscillator has a switching circuit or a timing circuit which controls an operating current of an amplifying element 8 for oscillation and reduces an average current in a TDMA operation without changing a voltage applied to a passive element constituting the oscillator. In particular, before initiating oscillation, elements in a negative impedance circuit are charged with a current of a value which does not cause the oscillation of the oscillator, and at the time of initiating the oscillation, a current capable of oscillating the oscillator is supplied to the negative impedance circuit.
