Frequency hopping oscillator and oscillator using it

摘要

Frequency oscillator that minimizes the charging and discharging time of a MOS capacitor and an oscillator using the same. The frequency subcarrier according to the present invention can eliminate the difference in charge / discharge time depending on the characteristics of the P-channel and N-channel Moost capacitors by connecting the P-channel and N-channel Mousse capacitors in parallel between the power supply voltage and the ground. The oscillator has a band-pass filter disposed on both sides of the frequency sub-carrier, removes noise through the filter, and fixedly sets the offset voltage, thereby stably maintaining the duty value of the oscillation frequency and minimizing the frequency deviation There is an advantage.
