Easy tunable oscillator based on current amplifier and diamond transistors with buffers is presented in the paper. Electronic adjusting of oscillation frequency is easy possible due to controllable current gain of used current amplifier. All capacitors of the oscillator are grounded. The characteristic equation, condition of the oscillation and parasitic influences of real active components are discussed. It is possible to verify the function of the circuit using commercially available devices what is strong advantage. The verification of functionality was provided by simulations and laboratory experiments.
