Abstract(in English) | When a packaged bipolar transistor is operated in a common-collector mode, the negative resistance at the base is exhibited without feedback networks. Thus, a negative resistance oscillator can be realized by connecting a resonator to the base. However, undesired oscillations were observed because frequency band where the negative resistance is exhibited is broad. The load impedance connecting to the emitter is controlled so that the frequency band with the negative resistance is narrow. In the experiments using prototype oscillators, suppression of the undesired oscillations was confirmed. |
