Controlled oscillator circuit for controlling an oscillator for use within a phase-locked loop |
摘要 |
<p>The output frequency (14) of an oscillator circuit (10) can be controlled by replacing at least one of the reactive components (40), such as a capacitor or inductor, with a synthesized element (22). The synthesized element creates a signal that corresponds to the response of the reactive component it is replacing. The synthesized element may be a current source (44), such as a field effect transistor, that is capable of operating at low voltages. <IMAGE></p> |
