A 6 W ±50 ppm/°C ±1500 ppm/V 1.5 MHz Oscillator Using Self-Regulation
IEEE Transactions on Circuits and Systems II: Express Briefs, 2018•ieeexplore.ieee.org
A low power RC relaxation oscillator with very low voltage and temperature sensitivities is
presented. Supply sensitivity is reduced by using a self-regulation loop that biases the
oscillator near its zero-voltage coefficient point. Fabricated in a 65-nm CMOS process, the
prototype 1.5-MHz oscillator consumes 6 μW from 1-V supply and achieves better than±50
ppm>° C and±1500 ppm/V temperature and voltage sensitivities, respectively.
