PROJECT TITLE :

Low-jitter, high-linearity current-controlled complementary metal oxide semiconductor relaxation oscillator with optimised floating capacitors

ABSTRACT:

A brand new complementary metal oxide semiconductor (CMOS) relaxation oscillator that includes with high linearity and low-jitter is presented in this study. The high linearity between the frequency and management current is achieved by adopting the floating capacitor and also the freelance charged and discharged loops. The low-jitter performance is gained as a result of of that the voltage across the floating capacitor is larger than the conventional oscillator. The proposed circuit is compatible with normal CMOS process and one take a look at-chip with typical frequency of half dozen.66 MHz was implemented in the 0.five μm (bipolar-CMOS-double-diffused metaloxide semiconductor (DMOS)) (BCD) process. The measured results show that <;zero.eighty sixp.c non-linearity in the current-frequency transfer operate from 1 to six.sixty six MHz without trimming. The cycle-to-cycle jitter was <;112 ppm.
