Abstract
Apparatuses and methods for temperature independent oscillator circuits are disclosed herein. An example apparatus may include a pulse generator circuit configured to provide a periodic pulse based on the charging and discharging of a capacitor and further based on a reference voltage. The pulse generator circuit may include a capacitor coupled between a first reference voltage and a first node, wherein the capacitor is configured to be charged and discharged through the node in response to the periodic pulse, a resistor and a diode coupled in series between a second node and a second reference voltage, and a comparator coupled to the first and second nodes and configured to provide the periodic pulse based on voltages on the first and second nodes, wherein a period of the periodic pulse is based at least on the resistor and the a current.
