Digitally controlled oscillator circuit |
摘要 |
A digitally controlled oscillator circuit for generating a signal at variable frequency is provided. The circuit has a data input for a digital control word and a capacitive circuit for varying the variable frequency of the signal. The capacitive circuit comprises a control input for a control signal and its total capacitance varies on the basis of the control signal. The data input and the control input have a mapping device coupled between them. This device is set up such that it ascertains the control signal from the digital control word. |
