Oscillator circuit

A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable medium and that, when executed by a processor, cause an apparatus to produce an oscillator circuit comprising:

• an amplifier comprising:
• a first transconductance amplifier comprising:
• a first input terminal;
• and
• a first output terminal;
• and
• a second transconductance amplifier comprising:
• a second input terminal;
• and
• a second output terminal;
• and
• a resonator comprising:
• a capacitor element comprising:
• a first capacitor;
• and
• a second capacitor;
• and
• an inductor element comprising a tapped inductor that comprises:
• a first segment of inductor comprising:
• a first terminal coupled to the first input terminal;
• a second terminal coupled to the first output terminal;
• and
• a fifth terminal;
• a second segment of inductor comprising:
• a third terminal coupled to the second input terminal;
• a fourth terminal coupled to the second output terminal and further coupled to the first terminal using the second capacitor;
• and
• a sixth terminal,
• wherein the first terminal and the fourth terminal are output terminals of the tapped inductor,
• wherein the second terminal and the third terminal are tap terminals of the tapped inductor, and
• wherein the fifth terminal and the sixth terminal are coupled using the first capacitor.
