Voltage controlled RC oscillator circuit |
摘要 |
A voltage controlled oscillator circuit is disclosed. A CMOS circuit version is detailed. A relaxation oscillator has its input coupled by way of a voltage follower buffer to the input terminal where the control voltage is applied. The operating frequency is determined by the circuit resistor and capacitor values along with the control potential. A linear frequency versus voltage response is obtained and the circuit will operate at low supply voltages.
