Abstract
An oscillator with a buffer circuit comprises: an oscillation circuit having an oscillation transistor; and a buffer circuit which has an amplification transistor and amplifies an oscillation signal outputted from the oscillation circuit by the amplification transistor. A power supply voltage is applied to the collector of either the oscillation transistor or the amplification transistor, the emitter of the other transistor has a D.C. ground connection, and the emitter of the transistor to which the power supply voltage is applied is connected to the collector of the other transistor via a resistor.
