Abstract
Examples are disclosed that relate to oscillator circuits. One example provides a circuit comprising an amplifier, a resonator in parallel with the amplifier, and a shunt path including one or more circuit elements, the shunt path coupled to a first node downstream of an output of the amplifier and to a second node, the shunt path configured to shunt current received at the first node away from an input of the resonator and toward the second node, the second node having, at steady state, a relatively lower voltage than an input voltage of the resonator.

A circuit, comprising:
- an amplifier;
- a resonator in parallel with the amplifier;
- and
- a shunt path including one or more circuit elements, the shunt path coupled to a first node downstream of an output of the amplifier and to a second node, the shunt path configured to shunt current received at the first node away from an input of the resonator and toward the second node, the second node having, at steady state, a relatively lower voltage than an input voltage of the resonator.
A circuit, comprising:
- an amplifier;
- a resonator in parallel with the amplifier;
- and
- a shunt path including a resistor, the shunt path coupled to a first node downstream of an output of the amplifier and to a second node, the shunt path configured to shunt current received at the first node away from an input of the resonator and toward the second node, the second node having, at steady state, a relatively lower voltage than an input voltage of the resonator.
A circuit, comprising:
- an amplifier;
- a resonator in parallel with the amplifier;
- and
- a shunt path including one or more circuit elements, the shunt path coupled to a first node downstream of an output of the amplifier and to a second node, the shunt path configured to limit current supply to the resonator by shunting current away from an input of the resonator and toward the second node, such that the current shunted away from the input of the resonator results in a drive level of the resonator that satisfies a non-overdrive condition of the resonator.
