【発明の名称】発振器の周波数ずれの補償
Document Type and Number:
Japanese Patent JP2000516430
Kind Code:
A
Abstract:
A frequency-drift ( DELTA F) of an oscillator (OSC) is compensated ( APPROX - DELTA F) by varying various different biassing parameters (V,I) in the oscillator. The biassing 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 biassing parameters (V,I) may be varied as a function of temperature by one or more elements with suitably chosen temperature coefficients and/or by one or more biassing circuits which provide biassing voltages or currents which vary as a function of temperature, or both.
