ABSTRACT:
An oscillator circuit (150) is designed with a reference circuit (102), responsive to a first voltage, for producing a second voltage. An oscillator (108), responsive to the second voltage, produces a first output signal having a magnitude less than a magnitude of the first voltage. A level translator (114), responsive to the first output signal, produces a second output signal having a magnitude greater than the magnitude of the first output signal. Since the oscillator produces the first output signal with a magnitude less than the magnitude of the first voltage, power consumption is reduced with respect to an oscillator operating at the first voltage. The magnitude of the first output signal is increased by the level translator to a desired magnitude of the second output signal.
