Breitbandiger Oszillator mit Vorspannungsausgleichung

摘要

An RF oscillator (10) is disclosed that can be tuned to operate over a wide range of frequencies while maintaining advantageous bias conditions. The oscillator includes circuitry (32) that adjusts an oscillator bias signal in response to changes in oscillator frequency and/or ambient temperature, and does so without resort to using the same signal for both bias and frequency control. By so doing, both the frequency range and temperature range of an oscillator can be extended, while simultaneously improving the oscillator's performance.
