Abstract: An oscillator circuit has a reconfigurable oscillator amplifier. The reconfigurable oscillator amplifier is used to be coupled to a resonant circuit in parallel. The reconfigurable oscillator amplifier supports different circuit configurations for different operation modes, respectively. The reconfigurable oscillator amplifier has at least one circuit component shared by the different circuit configurations. The reconfigurable oscillator amplifier employs one of the different circuit configurations under one of the different operation modes.

Abstract: A signal generator and an associated resonator circuit are provided. The signal generator includes the resonator circuit and a core circuit. The resonator circuit further includes a first inductor (L1), a second inductor (L2), a plurality of capacitors and a switching circuit. The first inductor (L1) has a first terminal (N1) and a third terminal (N3), and the second inductor (L2) has a second terminal (N2) and a fourth terminal (N4). The switching circuit includes a first switch (S1), a second switch (S2), a third switch (S3) and a fourth switch (S4). The core circuit further includes a first inner circuit, a first outer circuit, a second inner circuit, and a second outer circuit. Configurations of these switches are adjustable and resonance caused between these terminals is changed accordingly.
