초록/요약
In this paper, a voltage controlled injection-locked oscillator(VC-ILO) is proposed for wideband applications. From the control of the free-running frequency by a varactor diode, the wide frequency locking range can be obtained for low-level injected signals. The proposed VC-ILO is implemented on an FR-4 substrate with a thickness of 0.8 mm. The free-running frequencies of the oscillator is 2.39~2.52 GHz at the control voltage of 0~5 V. While the frequency locking range of over 50 MHz is presented for —10 dBm injected signal level at a fixed frequency, the locking range of over 90 MHz can be achieved for —30 dBm by controlling the free-running frequency.
