<P>PROBLEM TO BE SOLVED: To solve such a problem that it is difficult to avoid convergence to a spurious because the transconductance of an inverter is constant regardless of the oscillation frequency in an oscillation circuit where a resonance section and the inverter are connected in parallel, and to provide an oscillation circuit which can avoid convergence to a spurious. <P>SOLUTION: Power supply to an inverter is stopped when the pulse width of a one-shot circuit is larger than that of an input signal to the inverter, by using the one-shot circuit which outputs a pulse signal of a constant width at the transition point (rising, falling) of the input signal to the inverter. The time average of transconductance decreases in the spurious, and the oscillation does not last. <P>COPYRIGHT: (C)2013,JPO&INPIT |
