<p>A frequency-drift (ΔF) of an oscillator (OSC) is compensated (≈-ΔF) by varying various different biasing parameters (V, I) in the oscillator. The biasing parameters (V, I) which are varied may include, for example, voltages (V) or currents (I), either exclusively or in combination, which are supplied to transistors forming part of the oscillator (OSC). The biasing parameters (V, I) may be varied as a function of temperature by means of one or more elements with suitably chosen temperature coefficients and/or by means of one or more biasing circuits which provide biasing voltages or currents which vary as a function of temperature, or both.</p> |
