Series resonance oscillator

An oscillator comprising:

• an inverter comprising a first input and a first output;
• non-inverting buffer circuitry comprising:
• a second input;
• a second output;
• a first transistor having a first gate terminal and a first source terminal;
• and
• a second transistor having a second gate terminal and a second source terminal;
• a first inductor-capacitor (LC) tank coupled between the first input of the inverter and the second output of the non-inverting buffer circuitry;
• and
• a second LC tank coupled between the first output of the inverter and the second input of the non-inverting buffer circuitry, wherein
• the first gate terminal of the first transistor is coupled to the second input of the non-inverting buffer circuitry,
• the second gate terminal of the second transistor is coupled to the second input of the non-inverting buffer circuitry,
• the first source terminal of the first transistor is coupled to the second output of the non-inverting buffer circuitry,
• the second source terminal of the second transistor is coupled to the second output of the non-inverting buffer circuitry,
• the first source terminal and the second source terminal are separately direct-current (DC)-biased, and
• the first gate terminal and the second gate terminal are separately DC-biased.
