Abstract
An oscillator circuit having a programmable output frequency may include a first delay section having a negative gain and a variable delay that is set by a control signal provided to the first delay section. A second delay section having a negative gain and a fixed delay may be connected in series with the first delay section. The oscillator circuit may include an output comprising the output of the second delay section having a frequency that is dependent on the delay of the first delay section and the delay of second delay section.
