Title: Voltage controlled oscillator with variable frequency and duty ratio
Inventor: JU SEONG JUN
IPC: H03K17/13
Filed: 2001-07-05
Abstract: PURPOSE: A voltage controlled oscillator for controlling a frequency and a duty cycle is provided to independently control turn-on time and turn-off time by independently adjusting a charge time and a discharge time of a capacitor. CONSTITUTION: The voltage controller oscillator uses a charge/discharge of a capacitor in order to supply an output oscillation signal according to a control voltage. A voltage-current converter(100) converts the control voltage into a control current. A charge/discharge current generator(200) supplies a charge current and a discharge current to the capacitor and generates a difference between the charge current and the discharge current according to the control current from the voltage-current converter(100). A charge/discharge controller(300) supplies a charge/discharge control signal to control a charge current supply time and a discharge current supply time. An output signal generator(400) converts and outputs the charge/discharge control signal from the charge/discharge controller(300) into the output oscillation signal.
