Schwingkreisschaltung mit variabler Frequenz |
摘要 |
A voltage controlled oscillator (VCO) including a negative feedback circuit operates in response to a negative feedback signal generated during active transistor region operation of transistors in transconductance amplifying stages coupled thereto. As a result, harmonic distortion and problems of noise and unstable frequency oscillation are obviated or significantly reduced. The VCO includes first and second variable transconductance (gm) amplifying stages whose non-inverting (+) and inverting (-) terminals are respectively grounded and a first condenser connected between an output terminal of the first transconductance (gm) amplifying stage and a non-inverting (+) terminal of the second transconductance (gm) amplifying stage. A negative-resistive circuit is used to provide a negative feedback. |
