The present disclosure provides an oscillator circuit, a chip and an electronic device. The oscillator circuit includes two charge and discharge circuits, a reference voltage switching module, two comparators and a logic control module. When an output of either of the comparators, the logic control module controls one charge and discharge circuit connected to the comparator to discharge, controls the other charge and discharge circuit to charge, and controls the reference voltage switching module to switch a reference voltage of the comparator to a second voltage. When the output of the comparator transitions back, the logic control module controls the one charge and discharge circuit to charge. When the output of the comparator transitions again, the logic control module controls the reference voltage switching module to switch the reference voltage of the comparator to a first voltage, and controls one charge and discharge circuit to stop charging.
