VOLTAGE CONTROLLED OSCILLATOR |
| 摘要 |
<p>A voltage controlled oscillator having an operational amplifier connected to receive a known voltage from a reference voltage source and the output of a switching regulator circuit. The operational amplifier provides an output signal which is utilized after amplification by a transistor as an input to the resistive input of a current mirror of a pulse width modulator. The pulse width modulator is capable of providing a digital pulse stream as an output having a frequency in the range of 0 to 400 KHz in response to the output of the operational amplifier. 18</p> |
