Abstract

A signal generator configured to generate an oscillating signal with a temperature-compensated frequency. The signal generator includes a ring oscillator, and a complementary to absolute temperature (CTAT) current generator configured to generate a CTAT current for the ring oscillator to temperature-compensate the frequency of the oscillating signal.
