ABSTRACT:
A tunable oscillator circuit provided with a pair of oscillator transistors whose bases are crosscoupled to the opposite collectors, and provided with a capacitance which is arranged between the emitters of the oscillator transistors, each emitter being AC-connected via an emitter current source to a reference voltage is disclosed. In order to considerably increase the tuning range without being limited in the choice of the output amplitude, a pair of buffer transistors in common base configuration is added whose two collectors are connected via a pair of collector resistors to a supply voltage and constitute an output of the tunable oscillator circuit, said pair of buffer transistors arranged in a cascode configuration with the pair of oscillator transistors by being coupled to the collectors of the oscillator transistors.
