Classification: CPC H | IPC H

Claim 5:
6. The PLL of claim 1, wherein the oscillator includes first and second ramp capacitors, wherein the first ramp capacitor is configured to charge in response to a voltage at the oscillator output being relatively high, and to discharge in response to the voltage at the oscillator output being relatively low, the second ramp capacitor is charged in response to the voltage at the oscillator output being relatively low and discharged in response to the voltage at the oscillator output being relatively high, and the oscillator is configured to switch between providing the relatively low voltage and providing the relatively high voltage at the oscillator output in response to either the first or the second ramp capacitor having a voltage that is at least as high as a reference voltage.
