<p>A single stage voltage controlled ring oscillator (20) includes a trans-admittance voltage-to-current circuit (22) coupled to a trans-impedance voltage-to-current circuit (24). The output of the trans-impedance circuit is connected to the input of the trans-admittance circuit. The trans-admittance and trans-impedance circuit are preferably conjugately matched and may be coupled to each other via one or more transmission lines, the length of which can be selected to set a desired nominal oscillation frequency. The trans-impedance and trans-admittance circuits may also include voltage-controllable components which can be adjusted to tune the oscillation frequency. <IMAGE></p> |
