    摘要： An apparatus and method for providing an output signal. The apparatus comprises an input for receiving a reference signal, an oscillator for providing an output signal, and an offset signal generator for frequency multiplying the reference signal to generate an offset signal that has a plurality of frequency products in a plurality of frequency bands. The apparatus further includes a mixer for mixing the offset signal with the output signal to produce a combined signal, an offset frequency selector for controllably selecting a frequency band of the offset signal, and a difference detector for detecting a difference between the reference signal and the combined signal and for providing a control signal to the oscillator based on the detected difference.

    摘要： A Voltage Controlled Oscillator (VCO) mitigates the effects of package parasitics by providing positive feedback connections (50), to sustain a desired oscillation, external to the IC package, thereby mitigating the effect of the bond wires and internal parasitics to allow the oscillation to be controlled by the desired external components. The VCO includes an electronic circuit (20) with gain that is at least part of an integrated circuit (IC) and a package for the IC. A passive resonant circuit (10) may be provided external to the IC package. The positive feedback of the electronic circuit is provided through at least one additional lead of the package (50), such that the connection is external to the package.
