Title: Voltage controlled oscillator
Inventor: SATO MASARU
IPC: H03L7/187
Filed: 1989-05-12
Abstract: PURPOSE:To reduce the settling time with simple operation by selecting a bias voltage applied to a varactor capacitance diode and setting a time to the required time for a time till a frequency of an output signal is changed according to the change after the control voltage is changed. CONSTITUTION:The setting time depends on a bias voltage applied to a varactor diode. In such a case, 1st and 2nd capacitors C1, C2, a strip resonance line L0 and a varactor diode VD1 are components for an inductance section I deciding the resonance frequency of the Colpitz oscillation circuit. Thus, when the control voltage Vcont is applied via a high frequency cut-off coil L to the cathode of the varactor diode VD1, the capacitance of the VD1 is varied with the control voltage Vcont. Since the oscillation frequency of the Colpitts oscillation circuit is changed, the output signal (f) having the frequency corresponding to the control voltage Vcont is obtained from an output section of an AMP A1.

The address converting device 4' has the function equal to that of an address converting device 3 and develops the continuous address outputted from the input/output device 5 to a physical address on the main storage in page units. In this case, various tables in the address converting device 4' are rewritten by an operating system to freely allocate respective pages on the main storage device.
