Abstract
Systems and methods are disclosed herein to provide improved oscillator techniques. For example, in accordance with an embodiment of the present invention, an oscillator includes at least a first current source to generate at least a first current for capacitors that provide input signals for corresponding comparators. The comparators compare the input signals to reference signals and provide the results to a latch, which provides an oscillator output signal and controls the charging and discharging of the capacitors that provide the input signals.
Claims20
An oscillator comprising:
- at least a first current source adapted to generate at least a first current and a second current;
- at least a first and second capacitor responsive to the first and second current, respectively, to provide a corresponding first input signal and a second input signal;
- a first comparator adapted to receive the first input signal and compare to a first reference signal to provide a first comparator output signal;
- a second comparator adapted to receive the second input signal and compare to a second reference signal to provide a second comparator output signal;
- and
- a latch adapted to receive the first and second comparator output signals and provide at least one oscillator output signal, wherein the at least one oscillator output signal controls a charging and a discharging of the first and second capacitors that provide the corresponding first and second input signals.
An integrated circuit comprising:
- means responsive to a first and second current for providing a first and second input signal;
- means for comparing the first and second input signals to at least one reference signal to provide at least a first and second signal;
- and
- means responsive to the first and second signal for providing at least one oscillator output signal, wherein the at least one oscillator output signal controls the providing means for the first and second input signal.
A method of providing an oscillating signal, the method comprising:
- generating a first and second signal;
- comparing the first and second signals to a first and second reference signal, respectively, to provide a first and second comparator signal;
- and
- providing a first and second oscillator output signal based on the first and second comparator signals, wherein the first and second oscillator output signals control the generating of the first and second signals.
