DIGITALLY-CONTROLLED OSCILLAT0R WITH IMPROVED LINEARITY

摘要

The present invention relates to a digital type oscillator which includes: a resonance circuit part (100) which generates a resonance signal according to equivalent capacitance which is formed by a parallel connection between first capacitance (C1) which is varied according to digital control codes (DC) and second capacitance (C2) which is varied according to inverse digital control codes (IDC) which are reversed from the digital control code and a predetermined inductance; and an oscillation circuit part (200) which forms an oscillation condition for the resonance circuit part (100) by providing a negative resistance for the resonance circuit part (100). [Reference numerals] (120) Inductance circuit part; (200) Oscillation circuit part
