Voltage-controlled oscillator including current control element |
摘要 |
An odd number of inverter circuits are connected with each other so as to form a ring. A first current-control element is provided between an oscillation signal line which is used for connecting adjacent inverter circuits and a power-source-potential point, a current flowing through the first current-control element varying by a first control signal. A second current-control element is provided between the oscillation signal line and a ground point, a current flowing through the second current-control element varying by a second control signal.
