1. An apparatus comprising:
an oscillator to generate a clock signal, the oscillator comprising:
at least one resistor;
at least one capacitor; and
a circuit coupled to the at least one resistor and the at least one capacitor, the circuit to generate the clock signal;
a voltage regulator coupled to the oscillator to provide a regulated voltage to the oscillator; and
a bulk voltage generator coupled to the voltage regulator, wherein the bulk voltage generator is to provide a first bulk voltage and a second bulk voltage to the voltage regulator to provide temperature compensation to the oscillator.
