ABSTRACT:
A low power consumption oscillator circuit. The oscillator circuit comprises a capacitor coupled to a first resistor that is capable of delaying discharge of the capacitor. The oscillator circuit further comprises a first inverter coupled to the capacitor and having a first input. The first inverter is capable of applying charge to the capacitor when a first voltage potential on the first input is above a first threshold voltage of the first inverter. The first inverter is capable of removing charge from the capacitor when a second voltage potential on the first input is below a second threshold voltage of the first inverter. The oscillator circuit further comprises threshold detection circuitry having a second circuitry is coupled to the first input of the first inverter, and the second input is coupled to the capacitor. The threshold detection circuitry is capable of applying the first voltage potential on the first input when a third voltage potential on the second input is below a third threshold voltage of the threshold detection circuitry. The threshold detection circuitry is capable of applying the second voltage potential on the first input when a fourth voltage potential on the second input is above the third threshold voltage of the threshold detection circuitry. The third threshold voltage of the threshold detection circuitry is different than the first and second threshold voltages.
