Circuit for removing noise components of oscillator |
摘要 |
<p>Disclosed is a circuit for removing noise components included in a signal which an oscillator generates by using an integrator and hysteresis characteristic. The signal is oscillated by an oscillator. A square-wave generating inverter receives a sine wave signal including noise components oscillated by a quartz crystal oscillator circuit and then generates a square-wave signal having improved RC and integrator characteristics, and provides the generated square-wave signal to a Schmitt trigger. The Schmitt trigger receives the square-wave signal including the noise components from the square-wave generating inverter and removes the noise components included in the received square-wave signal. The circuit can remove noise components included in a signal oscillated by an oscillator due to a surrounding influence such as a temperature. Therefore, state clocks which is used in a microprocessor and a microcontroller, may be generated. <IMAGE></p> |
